1999 ML 320,Key fob wouldn't function to lock or unlock vehicle, when opened door manually and put key in ignition.....got nothing, not even a click. Battery had power and jump start still yielded nothing when key turned but lights came on and radio would play.

Mechanic say's it is AAM.

Anyone had this experience, and what was the cost to fix ??

 

Have you tried to resync the key?? Why dont you buy new batteries and try to resync. An AAM is roughly $2K...

 

THE AAM IS ABOUT $350 AND TO PUT IT COULD RUN YOU A NOTHER COUPLE HUNDRED.

 

The AAM in his 99 is the first generation AAM and has the DAS (Drive Authorization system) integrated with it so it is very expensive to replace. The AAMII, which is in your car and has the DAS separated from it, is about $350- $400 for the part and the labor to install about what you said.

 

where is the aam module located on a 2001 ml320
