We bought our '99 ML320 used in 2000 and it came with two remotes. One of them never worked and ther worked great until the wife let it get soaked with beer at a car show (long story).

I've taken them apart (it's not too hard but you do have to be careful) so swapping in new guts does not sound like too hard but... how do you get it re-coded to you car or do you code the car to the remote?

Our backup might be broken too or it might simply be coded incorrectly. How does one do this and is there anything I need to know before buying new remotes? And how much *cringe* do these things typical cost.

Since the car show incident we have been opening the car with the key (real pain when you have two kids!) so when it get back from the body shop I'd like to have both remotes ready to go.

Any pointers are appreciated!
