Reprogramming smart fob keys

Recommended Posts

Hi,

Does anyone know how to programme these smart fobs? My Alphard came with 2 of these and remote engine start fob.  They don't work and I don't think are for my car but need to reprogramme them to work.

Thank you

Follow this to the 'T' and it should work no problem with the smart fobs to open and close the doors (It looks convoluted, but worked for me on 1st attempt)

Before starting make sure you have no mobile phone in your possession/close by.

1. Sit in the drivers seat - Driver door open, key out of ignition 

2. Within 5 seconds, place key in ignition and take it out x 2 (Do not turn key)

3. Within 40 Seconds, close the drivers door and open x 2

4. Put key back in ignition (Do not turn key) and take it out

5. Within 40 Seconds, close the drivers door and open x 2

6. Key back in ignition and leave it in

7. Close drivers door

8. Turn key in ignition (Without starting car)

9. Turn key back and take key out of the ignition

(The door locks should automatically do a cycle - If nothing happens, you've done something wrong and will have to restart the re-programming again from the start)

Once the door locks have did their cycle :

10. Within 40 seconds press lock and unlock buttons on fob together for 2 secoonds

11. Then press lock button on fob for 2 seconds (The door locks should do a cycle again, if they do not complete a cycle, repeat step 10 and 11 again. If the door locks cycle twice, it also means that the re-programming has failed so repeat steps 10 and 11 again)

Awesome thank you so much 🙂 I have fixed it now just needed new battery 🙈 however my actual key is very worn so need to buy new one from eBay and reprogrammed it so hoping the above also works for the chip key
