    I have tried the the solution and it works only the one time when you do step 3 and that is from inside the vehicle. Are there any other possible solutions, or am I suppose to do these step every time I leave the vehicle?

Keyless entry doeasnt work


if its factory keyless entry, chances are your battery for your remote need to be replaced, the remote could also need to be reprogrammed... If it is an after-market system, there are several possibilities... wires could be pinched, the door lock solenoids could be broken or misaligned, the "brain" of the system might need to be reprogrammed.

My 1998 mercedes ml320 starts for 1or 2 seconds and then stalls.


You either have to replace the battery in your key fob or have it reprogrammed. Verify this by trying the second key, if you have it. AAA told me that you can reprogram it by leaving it in the ignition, with the key turned to the first position, overnight. I haven't tried it.

The batteries are flat like a nickel. the smaller end is the negitive end, the larger silver end is positive. Look inside the remote it will have marking corrisponding to the positive and negitive marks on the batteries.
