Hello from France (where Lexus is a rare bird),
Had the Lexus IS200 only since September 2004, its a 2002 model.
I got this central locking issue, since less than a week:
- remote control wont work
- auto lock security (after XX seconds) wont work either
The auto lock (not functionning) leads me to think its not an issue with the remote control, therefore not related to the problems with interferences, mentionned in a couple of topics.
All this started happening in various, remotely located, places. So my guess is it's really not related to a new antenna.
This is rather embarrasing, btw, since rear doors cant be locked with the key... so the car has to be left open! Or am I missing something?
I'd rather think its related to cold weather or humidity, and I am even starting assuming it is the reason why its previous owner sold it during the summer.
Anybody else had this problem before? Any solutions? Troubleshooting guides? The car's warranty is over ...
Cheers
