Issues with Programming Replacement Key ML500 2003
I paid $130 at the dealership to get the new key for my ML500 as original keys were misplaced. In the interin I have been using the spare Mickey Mouse key I bought a few years back from MB. When it can for programming ($65), SA told me that that new key cannot be programmed as sensors in the truck are bad and I will have to pay $350 to get them replaced. When I try to start with new key, it gives start and error on dash and egine dies immediatly as it starts.
If my spare key is working how can the sensor module be bad? Is there a chance that replacement key is bad? I asked the dealer to get a different key to eliminate this issue. He does not want to try that as it will cost him for the new key niether they will take the key back even if it is not working.
Is there anywhere else I can go to get this verified or is there any troubleshooting I can do to determine the issue? Please help!
