Uncut Transponder Ignition Key fits Toyota with 4C Chip, Set of 2

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.

Worked fine, you can program yourself, videos online tutorials. Be patient and follow closely. It will probably take a few tries but much cheaper than paying dealer or buying programming tool. If you aren’t tech savvy might want to just get the programmer

Absolute waste of time. I bought these for my 2001 Toyota Sequoia I ordered this key twice and both times I received defective copies that refused to program to my car. I did the procedure correct and everything yet they NEVER programmed I'm not convinced these even have transponder. I ordered a different set of keys, from a different listing and they programmed first try. All that tells me is that these are junk

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.

Got they key cut and it works perfectly

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 :)

The dealership wanted $600 plus labor to make copies and reprogram the keys. The locksmith about the same. We bought these and headed over to batteries plus where they copied and programmed the 2 keys and the 2 key fobs for a little over $100. So far no problems!
