USARemote Car Key Fob Keyless Entry Remote Start fits Ford, Lincoln, Mercury, Mazda (CWTWB1U793 4-btn) - Guaranteed to Program

Great deal on this key fob. Works well. You will need a locksmith to program it because there is a chip in it. I went to our local Ace Hardware store and they cut the key and programmed it a lot cheaper than a dealer ship.

Quite a savings if you live through the experience... :-) Here are some "key" points to help others out. This is for using these on a 2011 Ford 150 pickup truck, but I imagine they apply to many other fords. I needed to replace one key+fob that had stopped working (not the battery). It turns out the key has a security chip that was working, so just the fob had failed (would no longer open the truck doors). There are 3 parts to the adventure, and they can be done in any order. The new keys will only open the doors (manually) and start your vehicle after completing Part 1 and Part 2. The Key FOB works after Part 3 - so if you do Part 3 first, be aware the keys still will NOT start the vehicle. Part 1 = Cut the keys Part 2 = Program the security Part 3 = Program the FOB Note 1: You get 2 blank key+fobs with this order. They appear to match perfectly the originals. Part 1: Step 1. You will need to get the keys cut, this can be a hassle as some places will do it and others will not. They cut the keys - They do not program them for you. I ended up getting mine cut at Lowe's Hardware, even though they told me they are not supposed to do it. I love Lowes Hardware! Very helpful people. Note 2: There are two different components to program on each key+fob. The cut key itself WILL NOT WORK on the vehicle without programming the security chip - it turned on an automatic alarm when I first tried the cut key - Note the cut was fine, but I hadn't yet programmed the security chip. Part 2: Step 2. You need two working keys with working security chips to self-program a third key's security (as far as I was able to tell). Even though my key fob had stopped working, the key security chip was working so I had two working keys as far as security was concerned. I knew the security chip was still working because the key could still start my truck. Step 3. To program a third (and then a fourth) key security chip, I put the master key in and switched the car on (but did not start it). I then immediately did this with the second working key. I then placed the third new cut key in and when I switched the truck on the key security chip was programmed (or perhaps the truck learned the key's code, not sure). I repeated this for the fourth new key. (All of this is online in videos, I am telling it here so people know what to expect) Step 4. Once both new cut keys had their security programmed, they would open the doors (manually) and start the truck without setting off an alarm. Part 3: Step 5. The FOBs now have to be programmed. You place a working key into the ignition and switch the truck on then back off (again without starting the vehicle) quickly 8 times - on the 8th time leave the ignition ON. You will here the door locks operate - then push a button on the key fob you are programming and it should now work. I repeated this for the 4th (second new key) key as well. (Again, all of this is online in videos) Results: I now have 4 working keys (2 are new) and 3 working fob for a fraction of the cost of getting one through the dealership.

Programmed easily on my 2012 F-150. I had 2 original keys, one of which only worked the ignition, so with those two, I could program everything myself. 1. I first took the keys to Ace Hardware and had them both cut for $6! 2. Then I programmed the keyhead transmitter. This you can DIY if you have two working keys. 3. Finally, I programmed the fobs. Took less than 10 minutes to program the keyhead / fob. The fobs you can program with only 1 working key. Instructions below Keyhead transmitter programming (if your keyhead transmitter doesn’t program, the keys will turn but the starter will not engage and turn the engine over). 1. Insert the first previously programmed coded key into the ignition. 2. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least three seconds, but no more than 10 seconds. 3. Turn the ignition to the 1 (LOCK) position and remove the first coded key from the ignition. 4. Within ten seconds of turning the ignition to the 1 (LOCK) position, insert the second previously coded key into the ignition. 5. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least three seconds, but no more than 10 seconds. 6. Turn the ignition to the 1 (LOCK) position and remove the second previously programmed coded key from the ignition. 7. Within twenty seconds of turning the ignition to the 1 (LOCK) position and removing the previously programmed coded key, insert the new unprogrammed key (new key/valet key) into the ignition. 8. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least six seconds. The locks will cycle to indicate successful programming. 9. Remove the newly programmed coded key from the ignition. If the key has been successfully programmed it will start the vehicle’s engine and will operate the remote entry system (if the new key is an Integrated Keyhead Transmitter). The theft indicator light will illuminate for three seconds and then go out to indicate successful programming. Door fob programming 1. Close all doors, then open your driver side door and press the Unlock button on the drivers door while it is open. 2. Turn ignition from OFF to RUN 8 times within 10 seconds, with the 8th time ending in RUN. The door locks will lock and unlock to confirm that you have entered programming mode(Off is the position where you can remove your key, RUN is the position just shy of starting your car. If the door locks do not cycle you should try it again but faster. If they still do not cycle, your vehicle may not have keyless entry) 3. Within 8 seconds press any button on the first keyless remote to be programmed. Door locks will cycle to confirm programming. If you only have one remote then skip to step 5. 4. Within 8 seconds, press any button on the second keyless remote. Door locks will cycle again to confirm programming. Repeat step 4. for all other remotes. 5. Turn ignition to OFF. Locks will again cycle to indicate end of programming mode.

First and foremost: the keys work. A trip to my local Ace Hardware and within an hour they were starting the truck. I can see why a lot of people get confused in how to do this exactly. They try to explain the process, but somehow gets lost in translation. I’m not about to add more confusion to the pile. If you go slow, it’s actually fairly easy. Like others have said - and I can’t stress this enough - you MUST have two OEM keys (one master/one slave) in order to do this yourself. After reading/watching a few videos, and multiple attempts, I did get the “click-click” of the locks you want to hear. That’s the indicator it worked. The only problem I have is that remote start doesn’t work every time with the new keys. Maybe there’s more to program. At any rate, for a total of $20, I wouldn’t even hesitate to purchase again.

The chips are junk and will not program and are very cheaply made the business I went to could only cut the keys and the plastic housing is so thin it cracked just to open it. Cost me a lot of money to try and have it professionally programmed to no avail. Total waste of hard earned money. The chips are worthless in them and now I have to go buy own ones and spend $400 Due to this junk product. Buyer beware!

I got these keys cut at the dealership, then did the programming myself following these instructions. They work awesome, with acceptable but range but I will not complain for the price. REMOTE PROGRAMMING 1. Enter the vehicle, close, and unlock all doors using the power unlock switch on the driver’s door. 2. Insert the key into the ignition. 3. Within ten (10) seconds, switch the key as far to the ON position as it will go without starting; then back to OFF, perform this step eight (8) times ending in the ON position on the eighth (8th) time. Each cycle ON to OFF will count as one (1). If the door locks appear to be cycling after the fourth (4th) ON to OFF cycle, restart the procedure from STEP 1 and only turn the key four (4) times in this STEP, ending in the ON position the fourth (4th) time. At this point the vehicle door locks should automatically lock and unlock, indicating that the programming mode has been activated. If the door locks do not cycle automatically then the programming procedure has failed and you need to restart the procedure from STEP 1. 4. Within seven (7) seconds, using any remote, (we recommend first programming original remotes if you have one) press and release the LOCK button. The vehicle doors will automatically lock and unlock indicating the new remote has been accepted. 5. Repeat STEP 4 for all remaining remotes you wish to program (you can program up to four (4) remotes total). 6. Once you have programmed all your remotes, exit the programming mode by turning the key off and removing it from the ignition. 7. Test all remotes to ensure they are functioning. If any did not program, restart the programming procedure from STEP 1 and switch the order in which you are programming the remotes. KEY PROGRAMMING You must have two (2) factory keys that can start the vehicle to perform this procedure. If you do not have two (2) factory keys for the vehicle currently, a trip to a dealership or an automotive locksmith will be required for the programming. 1. Enter the vehicle and close the driver’s door. 2. Using the first factory key, insert the key into the ignition and turn it to the ON position as far as it will go without starting the vehicle and wait three (3) seconds; then turn it to the OFF position and remove the key. 3. Using a second factory key, insert the key into the ignition and turn to the ON position as far as it will go without starting and wait three (3) seconds. 4. Turn the key OFF and remove it from the ignition. 5. Using a new key, insert the key into the ignition and turn it to the ON position as far as it will go without starting and wait two (2) seconds. At this point the vehicle will illuminate the immobilizer warning lamp (usually a circular red light or car shaped red light on the dashboard display) for three (3) seconds, then the light will go out, indicating that the key has been programmed successfully. 6. Once you have programmed your key, exit the programming mode by turning the key OFF and remove it from the ignition. 7. Test the key to ensure it is functioning by starting the vehicle with it. If it did not program, restart the programming procedure from STEP 1. 8. To program additional keys, restart the programming procedure from STEP 1 and use the same two factory keys to program the remaining (you can program up to 8 keys total).

Purchased these to replace my 2 worn out key fobs. Called a professional locksmith who told me over the phone these are probably junk as he has seen subpar chip keys from Amazon before. I took the chance i may be that .01% that they are ok. He programmed them both, one had the start/door unlock programming wrong when hit lock button truck would start. Second one programmed ok but after a couple tries it quit working. The battery was dead. He replaced battery and it seemed to work fine. For all his work and programming and cutting it cost me $100 plus tax and now i only have one key that I’m not even sure it will work next time i use it. So, buyer beware that this is a problem that these cheap keys from china have bad chips and likely will not program properly. Spend the money and buy from a dealer or locksmith with knowledge.

Note that there are 2 programming procedures. One for the security chip. One for pushbuttons. I bought the two keys and because I only had one original, a locksmith had to program the 1st key security chip, while there he programmed the chip in the 2nd new key as well. I then programmed the fobs pushbuttons myself, refer to the sellers website for that…the website was in the pkgs for the new keys…. Re. REMOTE PROGRAMMING (buttons only, to program the chip its a separate procedure) “Please make sure to read through the programming before attempting. All remotes that are expected to work for the vehicle will need to be with you in the vehicle before attempting to program. Any remotes not present at the time of programming will cease to function until reprogrammed. 1. Enter the vehicle, close, and unlock all doors using the power unlock switch on the driver’s door. 2. Insert the key into the ignition. 3. Within ten (10) seconds, switch the key as far to the ON position as it will go without starting; then back to OFF, perform this step eight (8) times ending in the ON position on the eighth (8th) time. Each cycle ON to OFF will count as one (1). If the door locks appear to be cycling after the fourth (4th) ON to OFF cycle, restart the procedure from STEP 1 and only turn the key four (4) times in this STEP, ending in the ON position the fourth (4th) time. At this point the vehicle door locks should automatically lock and unlock, indicating that the programming mode has been activated. If the door locks do not cycle automatically then the programming procedure has failed and you need to restart the procedure from STEP 1. 4. Within seven (7) seconds, using any remote, (we recommend first programming original remotes if you have one) press and release the LOCK button. The vehicle doors will automatically lock and unlock indicating the new remote has been accepted. 5. Repeat STEP 4 for all remaining remotes you wish to program (you can program up to four (4) remotes total). 6. Once you have programmed all your remotes, exit the programming mode by turning the key off and removing it from the ignition. 7. Test all remotes to ensure they are functioning. If any did not program, restart the programming procedure from STEP 1 and switch the order in which you are programming the remotes.”

The keys work. Once cut, they program easily, but if you program the key fobs one at a time, any fob you’ve already programmed loses its programming. Also, the remote start button is there for show. Once the keys are programmed, they will unlock the doors, but not start the vehicle. There are cheaper options without the start option, so I recommend that if you don’t need the start button to work, but if you do, don’t bother with these.
