I have a Mercedes-Benz 2000 ML 320. I have 2 keys. One of them worked. But after i started the car with other key, my first key wouldn't unlock the car without putting the key in. It wont unlock the car with the remote. Any idea? Thanks in advance for your help.
To remove batteries, unfold key from holder by pressing lock button. Pull off battery cover.
Change batteries with Lithium, type CR2025 or equivalent by inserting new ones under contact spring, with plus side facing up.
Press battery cover onto housing until locked in place.
Test all buttons on remote.
If Remote still does not function, it may have to be resynchronized after changing batteries.
Sitting in the drivers seat with all doors closed;
Turn key in steering lock to position 2, then position 0 and remove.
Within 60 seconds, push and hold the lock button on remote for 15 seconds.
Now push the unlock button five times to activate the system again.
