If the old batteries were not completely dead, put them back in and see if the door locks work. (Sometimes batteries gain a little power once removed.)

Make sure they are facing down when you put them in.

Make sure you put the correct matching batteries in ...CR2025.

thanks sir slkman.. i tried it already i also tried a lot of fresh batteries.. but it still doesnt work.. what could the other reasons be?

Purely a guess but maybe it has to be reprogrammed by dealer?

Hope someone here with more knowlegde will chime in.

Sorry I can't help.

Hi Entrepid

I replaced the batteries in mine; you're supposed to do the reprogramming sequence described in the manual. Sorry can't remember the details but if you don't have them let me know and I'll look it up when I get home.

You can see if your batteries work by pressing the button on the keyfob and watching the little light flash -- two very brief little flashes, almost invisible, then one long flash is what mine do. The key seems pretty robust: I put mine on non-fast colours at 40 C and two hours in the tumble dryer without any problem.

Hope that helps.

Best regards,
Jonathan.

PS mine is a pre-facelift R170.

how do i reprogram the keys?

Hi Entrepid

Manual says:

Quote:

If you are unable to lock or unlock the vehicle with the remote control, the remote control may have to be resynchronized.

Aim transmitter eye at vehicle and briefly press transmit button LOCK or UNLOCK twice.

Within approximately 30 seconds insert key in steering lock and and turn it to position 2

The remote control should once again be operational.

Position 2 is normal engine-on position. (Position 0 is when you put the key in. Very German numbering!)

Hope that helps. I don't know if all the models are the same.

Regards,
Jonathan
