key won't work remotely

[slfabry]

I have had my ML320 for 4 years. It is a 2001. The remote locking/unlocking feature of the key suddenly won't work and I've already checked the batteries. I followed the operator's manual instructions to reset it, but instead it locks me in the car and sets off the alarm. Any suggestions?

Frustrated in California:-(

Obviously you've tried the spare key??

Was the battery disconnected just before it started to play up?

Have you tried a new battery.

Hold it in front of a digital camera

slf I would agre with Malcolm that even though you have replaced the batteries in the fob it dosent necessarily mean that it is working. Try as suggested in the previous post and come back with the outcome.

I have tried the extra key and had the batteries checked at a Radio Shack. Thanks for your ideas and your time however. Any more?

Dissconnect the main car battery.Leave it disconnected for at least ten minutes. Reconnect and try again. Come back with report.
