Toyota key programming. The Saga continued......

 I managed to finally nail a project I have been working on for about 6 months on and off. 

The challenge was set by mum to get her a replacement car key for her Japanese import V8. 

After some research, it turns out locksmiths don’t like Toyotas as the are difficult to ‘code’ a new key for import vehicles. I tried the main Belfast dealer and after being told that they ‘weren’t obliged’ to supply parts for import vehicles, i got the hint that they just wanted to sell new cars. If they had any brains, they could have had repeat customs for spare parts.... oh well, their loss. I decided to channel my anger in a positive direction and decided that if Mum was to get a sore key, I was going to have to make one!

First job was to buy a copy of Techstream online so that I could access the vehicles ECU. This gave me full dealer level access to the immobiliser ECU. 

I then ordered a spare key from a dealer online to match the Japanese frequency of the original master key. Once the key arrived, I removed the blade and took it to the locksmith so they could cut the blade and match it to the master keys pattern. I placed the we key blade and original electronics in the new shell case. This gave mum a good quality working master key. 

The challenge was then to duplicate the master key. I used the Ebay spare key I purchased and put the key blade into it along with the new RFID (the radio frequency chip). 

Techstream takes you through a procedure to then code the key to the immobiliser and match the RFID chip to the car. Unfortunately, it didn’t work!!! 

This meant I had a second key that would fit the ignition barrel but only turn the engine over, as the immobiliser wouldn’t inject fuel for the car to run.

After a bit of swearing, head scratching and more swearing, I got online and found that although it’s a Japanese car, it used a ‘Texas instruments ID68’ chip. I checked what the eBay key was and it turns out it was an ID67 chip. Even though it was ‘guaranteed’ to fit the SC430 V8. 🤬

I then searched online for an ID68 chip and found that a German company sold the actual RFID chips separately. 3 clicks later it was paid fob and on its way! 

The chip arrived today and I fitted it to the spare eBay key case along with the pre-cut blade. I fired up Techstream and it took me through a quick setup to link the key chip to the cars memory. 78 seconds later it told me the key was ready. Disconnect Techstream, turn the key.... and she fired!! 

Total cost was:

£24 for the second key fob, and blade.

£18 for the FCID chip delivered from Germany

£25 delivered for a copy of Techstream plus USB - OBDII adapter. 

How much from the dealer? .......quoted £330 IF they could find it. (Which they didn’t!) 

I deserve a glass of wine. Plus at the end of the day, I have one happy Mum!
