so i bought me a 2005 ml500 the remote does not work battery is good
check and swapped and found the relays are both good. if im sitting inside the vehicle i can lock all the doors
but i cannot use the key to unlock all the doors?
the gas door does not lock

any ideas, could it be discnnected due to a bad actuator?
but i shouldnt be able to lock the doors from the inside so confused
any help would be great thanks mike

 

The inside switch works on a completely different circuit.

Using the key remote, do any of the doors lock?

What relay numbers have you checked?

 

Try syncing your remote

 

so i wil try to see if i can reprogmam the remote/it currently is not working with the vehicle, i check the batteries aready/no infred so the instructions you set me i think will let me know if the transmitter is dead right?
anyway i swapped fuse k24 and k23.

thanks
