SOURCE: Brake lights stay on

Your brake light switch is stuck on, this is also why the cruise is in-op, the cruise is turned off anytime you touch the brake pedal otherwise the car would try to accelerate when you tried braking. The brake light switch is located above the brake pedal, look up the arm the pedal is attached to and you will see it, the switch is not real expensive, and it is easy to install with simple hand tools. As far as the door lock issue fix the brake light switch and try it, not sure it is related unless it all started at the time the brake lights started staying on. Post back after you replace the switch if door problem remains. Thanks

SOURCE: how do i disable alarm system????

under the rf floor board in the front you will see a false panel after removing carpet. remove false panel by loosening 10 mm plastic nuts your alarm module is 1 of the 2 modules on that false floor-it should have a 820 number in the part number-if it is not obvious call parts dept. and cross reference numbers-unplug module and you won't have worry about that annoying alarm anymore-hopefully i have been helpful

SOURCE: I have a 1995 Mercedes Benz s320 and my doors wont lock

There is a central door locking pump under the back seat, the motor has gone in it, cheap way to repair is to strip it down and put a motor in it from a tyre compreser from argos for under £10 very easy to fit just two wires

The alarm keeps going off for no reason i had to unhook the battery,what can i do?


Check for a battery drain ie:trunk light or glovebox light staying on
make sure all the door catches are closing properly spray the locks with wd40, Including the hood and trunk catches, check the radio is off properly, You made need to get a electrical drain check done by an electrical expert ?
Hope this helps

I removed the radio on my 99 c20 Mercedes now it wont start


Radio removal is not likely the cause.Check fuses, especially for alarm and door locks. Make sure door locks work (door locks and alarm are controlled by the same part). Make sure your battery isn't weak. Does the key turn? does the starter engage?

Alarm turns on when car is locked


Hello,
Does your alarm turn on ( it starts beeping) or do you mean that the car gets locked automatically once you close the door?
If it is option number one you will need to take your car to the dealer as the alarm for mercedes benz is link to the computer of the car.
If it is no. 2 it is normal for the car to do this
Thanks

Remove the factory alarm.
1) remove the passenger side floormats 2) unscrew the 10mm nut securing the kick panel to the firewall and remove the kick panel. 3) locate the black box that says "becker autoradio" on it. 4) unplug both cable harnesses from the box 5) remove the box (optional)
Put the kick panel and rugs back and you are done! Should take 10 minutes.

I have a 1992 mercedes benz 300ce and i cant get the alarm to shut off. ive tried unlocking and locking it again with all keys but i cant get it to shut off


You must turn the car on after alarm goes off. Door locking and unlocking dont work after the alarm goes off. Its like you break a window to get in anyone can lock or unlock a door thats why its tied to the ignition.

How do you disable the alarm on a mercedes benz 300E 1987


Use your door key and unlock your drivers door ... that is what disables the alarm system. Make sure that the battery is rehooked... because i'm sure you took the battery loose when you couldn't get the alarm to turn off.
