I get randomly a start failure with my 08 WH.
I have the following key:
Sometime, when I insert the key, I get the following messages:
'Key not programmed'.
The electrical steering lock doesn't work and no light at all.
I get this with the two keys I have.
I only have to remove the key and then insert it for being able to start.
I notice that I get more often this problem when it's wet: after having washed the car, I have to insert close to 10 times the key for getting started.
I think that the problem started when I have installed the dual color led turn signal where I got for one time this error.
I also got the following messages while inserting the key:
"Transmission overtemp" (just flashing message less than an half of a second)
«key battery low"
I replaced the battery on each key: no result.
I disconnected the main battery for around 10 minutes: no result (I only lost the autolock door )
I also refilled the battery as it was only at 12.3V but even after the refill, it was at 12.8 (I was sure that a full battery was at 13V or higher): no result.
