New Key Fob Pairing
 

Does anyone know if its possible to DIY pairing a new key fob to your Scion FRS. I would rather not pay a dealership to do this.

I did just perches the Carista OBD2 to turn off the passenger side airbag warning bell for when i place items in the seat and it thinks there is some one sitting there.

I was wondering if it also has any features for pairing new key fobs?

Anyone ever try and DIY this? I have an OEM Scion key fob from the dealership, i purchased the FRS used. But the cheap #### didn't have the fob programmed.

Thanks

Not so simple

If you are buying a genuine OEM key from Toyota the process is easy. You buy an $18 cable on Amazon and pair the remote and transponder with Techstream. The OEM key is expensive though. You can also buy non-OEM keys for cheap and programing the remote is easy but the transponders on these non-OEM keys are not compatible with our car even if the product description claims they are. Our car uses a Toyota remote but the immobilizer system is made by Subaru. It isn't the standard Toyota G transponder.

Some other things to know about pairing transponders is you need a master key to program another master or valet. If you have lost all your keys you have to deal with the dealer. If you have a master you can buy a valet for $60 and program that and then put your master in a safe place where it will not get lost.

So here is a cheap option. Buy a non-OEM keyfob simply to get a remote and blade. Then order a $60 OEM valet. Then you pair the non-OEM remote, cut the key, pair the OEM valet and then cut the valet key open and remove the chip and then place the chip in your non-OEM key fob. So now you have working key that will unlock the doors and start the car for around $100.

Another option which I think would work would be to buy just the front cover of the OEM master key. It sells for about $60. The chip is pressed into the front cover and I'm fairly sure if you order a front cover it will include the chip. So then you would buy a cheap non-OEM key to get the blade and remote but use the chip from the OEM front cover.

I just found this on google. Sounds line a snip hunt? Im gona give it a try.

Ahh but that is the trick. It isn't a Scion system.

I have an oem key i just need to pair it with the car. What cable do i need off of amazon?

Well it didn't work and i just felt stupid trying it. Ill see if there is a suburb version of this to try.

There are about 50 threads on this subject here. Nobody has found an "easy" way to do it. As Ermax says in the post above it is the transponder that is the issue.
Think about it. If the transponder was as easy to program as opening a door and turning a key a certain number of times it would suck as a security device. There are no shortcuts to get around proper programing.

As long as it’s an OEM transponder you run Techstream and select the option to pair a transponder. It asks you to insert your original master key. Then click next and then insert your new key. It sits for a bit and then says it’s done. The key is to not bother with 3rd party transponders. They are all Toyota G chips which isn’t what we need on our unique car.

Just search for Techstream. There are tons of them.

I had a locksmith come to my house and sell me a new (aftermarket) key and copy my existing key for about $200. Dealers were quoting 450-600 around here which is a joke.

The aftermarket key works fine except for the trunk release button the key (i dont care). This is a push button start model.

(i know you were asking about DIY but aftermarket keys work fine)

I would love to know exactly where he got this aftermarket key. I’ve tried a bunch of aftermarket keys and none of them have the correct transponder for our car even though the product description specifically says it does. As for the trunk release. All of the aftermarket “remotes” I have purchased have had working trunk release buttons. I don’t have a push button start so maybe that is the difference. Or maybe you have that button inside the trunk pressed which disables the trunk release.

I've been down this road...there is no magic bullet for a ToyoBaru...


zoomzoom (hey that's a Mazda saying isn't it?) just go to the dealer and buy a new key/fob & schedule an appointment to have it programed...IIRC $425 later you will have what you need and a lot less stress...

I did mine with a local locksmith with a OEM (after buying an aftermarket one and not working) Key for under $200.
