HI my dear old dad has a 1996 300D but he is having problems. The alarm will set to lock the car but more and more it will not reset and the imobliser will not let the engine start.We have been through the process of resetting by the owners manule but still it dose not cure the problem.Dose any kind person know how to remove/disengage and in desperation rip out the alarm/imobliser.Hope some body can help

Many thanks still not working but we think it might be the siren shorting out plus the internal batteries will not hold a charge.I dont anybody knows the part numbers for these items

The MB Pt. No. should be written on the siren itself, good luck in locating one though as I believe they have been discontinued, but please try them first. I bought one from Merc man (breakers) they had a number of new ones.
You could try opening up the siren box up and replacing the internal batteries as 9/10 thats the only thing wrong with them.
