Advice with key activation

[gregrsv]

Hi
Ive had issues with my keys on the 02 landruiser vx , i bought the vehicle with a non remote grey toyota key ( doesnt fit the glovebox so i'm guessing its a valet key) ive used this key constantly and it's fine and all works.
The remote keys were in a bag with new fobs to be installed , so ive built the keys up , the first key ive tried is the same cut or pattern as my grey key and following internet instructions ive got the central locking and alarm operating , but it still will crank the engine without engine start so the immobiliser isnt liking it!
The other fob key i havent tried yet but being a different cut i thought it might be he wrong key although ive heard the aster is a different cut. i didnt think it would be a remote key though which this is.
Any ideas what i should be doing guys.
cheers
greg

I honestly can't remember much about it but my Mrs had a similar problem with her Rover years ago , we couldn't get a sensible answer from Rover and the internet just offered contradicting advice so in the end we took the car to a fella who specialized in car electrics to have the immobilizer , central locking etc disabled thus making the key just a key in the old fashioned sense . What a sound bloke he turned out to be , on hearing of our problems he just took the key put it in the car door and (for example) turned the key 4 times to the left , then 3 times to the right , then 5 times to the left again , like he was entering a combination on a safe . He handed the keys back to the Mrs saying try it now . Everything worked as it should perfectly ?

I suggest having a read on mud. There are a few threads there, some with recipes for reprogramming for different model years.

I bought new uncut keys from DX, had them cut at a local high-end keysmith (inner milling), swapped over the remote module (containing also the immobiliser responder) from the old key, and have been happy since
That's when you have the old module tho'. If not, you have to program the new one into both the engine ecu and the ecu for the door locks.
