Key Programming

[flash22]

The chip is inside the button case

OK, got it. I prized open the button case and presto, the tiny chip is located in place.

hold that chip near the ignition and turn the key and see if it starts

[flashclick]

Um. Sorry. I don't understand. The chip is inside the key you want me to put into the ignition, so you want me to take the chip out first?

[flash22]

The immobilizer ring is around the barrel, hold the chip/buttons as close to it as possible, then turn the key and see if it starts

the chip maybe weak, the closer you can get it the better chance it may read it

Taking the chip / button insert out of the fob key case, holding it up to the barrel whilst trying the key in the ignition did not start the engine. I also tried using the grey key against the barrel which allegedly has a chip embedded. It did not help. The grey key DOES start the engine, of course.

Ok that chip may have failed, get a replacement chip, ideally you need to find out if the chip can be read

If you dont mind the trip i will be happy to give the programming a go/see what i can do

I can buy a chip from the info on the web. Then, what do I do to find out what you need to know?

I have just watched the video posted earlier with great interest as my 2022 Yaris was stolen after thieves broke in to our house and made off with both keys. Fortunately I had loaded the Toyota app which told me were the car was and the police have recovered it but as it's locked can't as yet get in it to get forensics. A new blade key has been ordered and that has to come from Germany, nearly two weeks later and it still hasn't arrived.When the police are done, it has to be moved to the Toyota dealership who estimate it will cost £3k to reprogram the car. It seems they are suggesting the ECU has to be replaced but that is not what the video suggests is needed. I'm not technically minded..but can someone tell me in simple terms...can the dealership acquire the CED number ( I think that's what he was referring to but I might have the wrong spelling)  from Toyota and reprogram the car that way?

While there are apparently alternatives, the stance of the whole UK Toyota dealer network seems to be that, if you have no 'master' keys, they have to replace all the locks and the ECU that holds the key codes.

That said, newer cars come with a key code on a metal tag which I was told they could use to make new keys?

But is this your problem anyway? I would think this should all be dealt with by your insurance...?

If not by theft, then lost keys?

You are correct I guess. It's for the insurance company to argue I guess. I haven't even informed them yet as I am abroad on holiday still and at over £2 per minute I'll wait until I get home. My son tried phoning on my behalf and was left hanging on in a queue for 15 minutes with an estimate of another 20 minutes to go. I told him to give up.

Incidentally I'm not aware of any metal tags with key codes being given to us but they would still need to be changed to stop the thieves simply taking the car back. Currently it's in police custody where I'm happy to leave it for now.

Holy flying cows those are some hefty roaming charges!

Usually the small metal tag with the key number on is on one of the keyrings supplied with the car. It is fairly common for manufacturers to include these metal tags when a new car is collected. We always make a note of the key number in the service and warranty book in case the tag gets mislaid.

They key tag is never really needed, if you order a new key from me, I don't use the tag number, I order it via chassis number 

[Cyker]

But you still need a master key to pair it to the car...? Or is that not needed with newer cars?

 

[Parts-King]

Some cars can be reprogrammed by a key specialist, most not, you nearly always need a master key. I have a really good guy I use, he can't do some models at all (Aygo) in particular 

[flash22]

If it's keyless, pop into techstream with remove the keys, re-sync the immobilizer then add the new key, the master/slave key setup was phased out in 08 ish

the main dealer will have access to techdoc with the required security clearance, iirc it costs £1.50 or so

The ecu can also be factory defaulted

Have you made any progress ?

[DaveinWales]

The slip key finally arrived from Germany at my local Toyota dealers and an officer was dispatched to pick it up so they could get on with the forensics. While he was there he was given a key that someone had found on the beach not far from where the car was recovered. Amazingly it turns out to be one of ours so it saves the insurance company a huge bill. The thief/ves must have attempted to throw the keys in to the sea when they discovered the car wasn't were they had left it. Sadly there was not much of our stolen property left  inside the car though.

[flash22]

Thanks for the update, at least you have a key so they can now program 2 new keys and remove the old ones

let's hope that can nail these scum
