Ls400 Immobiliser


Recommended Posts


I have recently had my 1995 LS400 in for a timing belt change and now it won't start. The mechanic removed the neg lead on the battery and the immobiliser won't allow the car to start. The only problem is I have neither key fob or immobilser key. I only have the ingnition key. Is there anything I can do to get round the immobiliser?

Same problem here, except it was the starter that was replaced.

Have tried this.


..and some key tricks involving opening and closing doors locking and unlocking and generally dancing like a monkey. still nothing....

...I called Scorpion (the company is gone but they still have support in the UK on +44 01257249928) no joy there either, they said hold the black button on the remote for 10 seconds. doesn't work.

next I'm calling Lexus in hope of some inspiration.

Anyone got any pointers/had this problem?

Hmm, not sure if this will help, but I found this:


Are you sure you have an immobiliser? I'll have to check my 95. According to the link above, only 97+ have them. This thread seems to confirm it: http://www.clublexus.com/forums/ls400-foru...mmobiliser.html

hombre, your mechanic must not have connected something back correctly. Something else is causing your car not to start.
