Key fob

So I have a key fob from a '21 limited and wanted to know if it will work on a '22 . I know that it will have to be reprogrammed but the key fob is a different shape will it work?

Not sure to be honest with you?

I know in the earlier days of keyless entry and smart key stuff, if the frequency the keyfob operated on was the same you could usually program them to a vehicle. That's how some people "upgraded" some of their smart keys to a Lexus Keyfob for the nicer look.

But Toyota has been doing a some odd stuff lately when it comes to the Smart Key stuff... i.e. they apparently consolidated the Smart Key & TPMS Antennae modules in Rav4 and Highlander into one unit in the last couple years... so if you have a Highlander with a smart key it actually has TPMS sensors that operate on a different frequency/signal, you can't program say a second set of wheels from a non-smart key car to that highlander (we ran into something like this with a customer and their winter wheels).

So it might not be possible to program that key to the vehicle even if the frequencies matched. It's not something we normally do or have been asked to do and I'm kind of turning up a little empty on information whether or not anything besides the visual design of the key changed in '22.

Here's what I believe; the car has the learning device in it so when a new key is programmed it's the car that make the changes to learn the frequencies from the key. This tells me that a key that works on another vehicle could be programmed to another.

Get ahold of Tom's Keys. They rent key programming equipment for a reasonable fee. They have a lot of info and can almost definitely answer your question. I recently used them to program 2 keys for my rig. They are not smart keys and I know there are some differences there but they do have smart key programming tools. Their customer service is pretty good. I had questions prior to spending any money with them and they promptly answered all of them via email. They also have a few YouTube videos on the whole process but your specific question hasn't been addressed that I've seen.

To be clear, the operating frequency is different from the coding for the actual security key code.

The frequency is the band that the key transmits data on, i.e. 315Mhz for example. The security key code is the data it transmits and receives. If the key is transmitting on say 315Mhz and the car is 300Mhz, it will never see the key fob's security key code.

2022 Fobs are completely different.From what I understand the new 2022 keyfobs are different and more secure and have to be done at the dealership. This is a good thing to prevent theft.

Here's a post from lexus forum Programming a new Key fob - ClubLexus - Lexus Forum Discussion
on copying the new keys which we have now too.

Also in this thread...Activating 3rd Smart Key FOB 2022 TRD PRO

Quote from forum:
Unlike the traditional 96-digit seed number which can be cheaply deciphered using a code calculator, the new data1+data2+data3 type of seed number has not been cracked at all. The only way to pass through it is by acquiring the pass-code from Toyota's TIS Security Professional subscription.

The 4runner went to this much more secure technology for 22 but other Toyotas went last year and the year before. It keeps thieves from copying the codes remotely ,so a lot have gone to using the OBD port to steal them apparently.
