Uncut Transponder Ignition Key fits Toyota with 4C Chip

I bought two of these for a 1999 Toyota Avalon XLS. They cut fine and work well mechanically turning on the ignition. The attempted programming of the transponder chips has been a nightmare.The website that the card with the keys, sent me to a website that after entering the make, year, and model of my car. Listed instructions for adding additional key fob remote lock/unlock transmitters etc. It did not have any instructions for adding key transponder chip keys.Please understand, I have spent hours searching and trying different methods of programming Toyota’s. Some were supposedly for my exact car but so far I have gotten no where. I guess if I only accidentally lock my oem key in the car I can get in with these keys but if for what ever reason I lose my original keys then I am in for a costly world of hurt which is what I was trying to avoid by buying these in the first place and as near as I can tell according to all of the information listed these should work on my car. Based on personal empirical experience. They do not! I have dealt with computers all my life. I understand programming electronics with instructions If the error is truly mine then communicate to me workable instructions. I was programming vcrs by the age of six.I am open to changing this review if my situation can be positively remedied.Two stars for keys that worked after being cut. Minus 42 stars because I am miffed and I just want it to work as advertised and that I paid for.[Update 02/26/20] After great consternation and frustration I have found that I lost the master key and I am using the sub key or valet key.Before ordering any transponder (chip) key, check your existing key and ensure that it is in fact the master key. Try unlocking or locking the glove compartment and/or the trunk. Only the master key will work on these.In order to program a transponder chip key, you MUST have the master key in hand for your vehicle.

I saved $140 by buying two keys from Amazon and programming/registering them myself and getting them cut at Home Depot. The locksmith was going to "cut me a deal" and only charge me $80 each. My 1999 Toyota Avalon requires keys to have a transponder chip for them to work, and they have to be registered to the car.I bought two "chipped" key blanks from Amazon that were the Toyota 4C type that my car requires. I got both for under $14, and they got here overnight. I registered the keys myself, in my car, using the procedure below. It was easy and took less than five minutes. Then I took the blank keys to Home Depot and they cut them for $3.50 each. They work great.This is the registration process (there are videos on YouTube):- Take your MASTER KEY (not the valet key) and insert it into the ignition . Do Not Turn! The flashing security light will go out if you have a master key. You must have a master key for this to work.- Within 15 seconds of inserting the master key, depress and release accelerator pedal 5 times.- Within 20 seconds depress and release the brake pedal 6 times.- Remove the master key.- Within 10 seconds insert the new "blank" key into ignition. The security light will continue to flash.- Within 10 seconds depress and release the accelerator pedal 1 time. Your car will start the registration process.- After 60 seconds security light will go off. The new key is registered.Repeat the process to register other keys.

I successfully programmed the keys in couple of minutes (YouTube: insert the original key (don't turn), press the Gas pedal 5 times, then the Brake pedal 6 times, take the key out and put the new one in (don't turn, you can do it with the key as is uncut) then press the Gas pedal one time and wait for a minute)Home depot and Ace refused to cut it for me, same with some locksmiths try to sell me their keys for $95 (Said that that keys will not work). Found an honest old fashion locksmith who cut the key for me for $2 each :)

I bought 6 of these keys overall. Key 1 and 2 programmed fine and worked well, but after a month key 1 chip stopped working which left me stranded.I bought key 3 and 4 to replace it, and both key chip were defective and would not program. I returned them and got a third pack of two keys. Before I received key 5 and 6, key 2 stopped working too and left my wife stranded.The key 5 and 6 programmed fine, however there is no telling if the chip will stop working and leave me stranded again.So far its money wasted and a very angry wife due to the being stranded when needing to picking up the kid. Not recommended.

I had trouble programming myself. Went to Toyota hours ago spend $101 to have them program. But the key actually works!!If you are needing another key for your vehicle this is worth the investment. Saved MAYBE an additional $100.

No issues with the key at all. But no one was willing to cut it for me at any bigbox store or hardware store. I had to get it done with a locksmith which was more expensive than I thought it would be...

I wasn’t aware I had to pay for a locksmith to program the embedded transponder which was $125 for each key. I went to Ace Hdwe and paid $100/ea for their proprietary keys to be cut & programmed saving $50. These keys ended up being useless.

I'm always hesitant about buying very cheaply priced things that would normally cost me a arm n leg to get if I was to buy it from a local store. In this case if I was to buy a blank unprogrammed key it would've been 200-250$ + just for the key not cut or programmed. (Prices are ridiculous where I'm from. Hawaii) Anyways over the past 3-4 years I've lost my Tacoma's keys 3 times. Every time I ordered a key I've gotten it from these guys. All you need to do is find a lock smith that cuts and programms the key and you'll have your truck rolling in no time. Big save of money . I've lost my keys so much I've become friends with the lock smith and now he charges me only 60 buck to cut and program . huge save worth every penny!

Funciona muy bien en mi Toyota matrix 2005 , se siente sólida la llave aunque sea ligera , fue fácil de programar y está funcionando sin problemas!

After our 2007 FJ was written off in a rear end collision we wanted another one to replace it. Bought a 2008 FJ and needed extra keys - these worked great.

Did not work on toyota sequoia

Works great. I was able to program the key for a 2003 Sequoia without any problems.I would give this product 5 stars but the key is bulky and plastic is slippery.

Ordered a week ago, delivered today, Had Keys cut and programmed the keys too my vehicle with supplied instructions, works great, Would buy again.
