    My ignition switch froze. It's the alarm, as the key works everything else except turning the ignition switch. I've disconnected the battery twice, changed batteries twice in the remote key. Still cannot turn the ignition switch.

Hello,
from your opening key button, on the car key, its a black,folding key. keep the opening button pushed until a red light apears in front of the key side. then start the engine. Both lights on the inside rear view mirror will blink.
then is reset.
hope will work.

You can't figure out thing's without knowing how there work , what controls them . In this case a control module .
Principles of Operation

Power Door Locks
The central security module controls the power door lock and keyless entry system. The lock and unlock operation is carried out by supplying ground to the central security module from the door lock control switch. The normal path of the actuators is to ground through the central security module. The door lock control switch will lock and unlock all doors by grounding the appropriate circuit to the central security module. The central security module then supplies power to the appropriate common actuator circuit to lock or unlock all doors.
Plus we don't guess , we test the electrical circuits with a DVOM - digital multimeter or a test light . We use a wiring diagram so we know which part of the circuits to test .

Keyless Entry
The remote transmitter sends a frequency that is received by the central security module internal antenna. Depending on the frequency received, the central security module will lock all doors or unlock the driver door. If the unlock frequency is received again within five seconds of the first unlock, the central security module will unlock all doors.
If the frequency received is for the panic button, the central security module will cycle ground to the park lamp and horn. The park lamps and horn will continue to cycle until the panic button is pressed again or the ignition switch is turned to the RUN position or 2.75 minutes elapse.
Plus we hook up a scan tool that can read codes from the control module , not a code reader for engine codes , won't work ! Need a professional scan tool .Do you know what DTC'S are ? Diagnostic trouble codes !
Central Security Module Diagnostic Trouble Code (DTC) Index DTC Description Source Action to Take B1309 Power Door Lock Circuit Short to Ground Central Security Module Go To Pinpoint Test C . B1341 Power Door Unlock Circuit Short to Ground Central Security Module Go To Pinpoint Test C . B1485 Brake Pedal Input Circuit Short to Battery Central Security Module Go To Pinpoint Test E . B1526 Keyless Entry Circuit Short to Ground Central Security Module Go To Pinpoint Test F . B1629 PRNDL Reverse Input Short to Battery Central Security Module Go To Pinpoint Test E . B2276 Less Than Two Transmitters Programmed Central Security Module Go To Pinpoint Test I . B2425 Remote Keyless Entry Out of Synchronization Central Security Module Go To Pinpoint Test I . - All Other DTCs Central Security Module REFER to Section 419-10 .
  • All door locks are inoperative
  • Battery junction box (BJB) fuse(s):
    • 8 (15A).
    • 115 (20A) (Super Crew).
  • Circuitry.
  • Central security module.
  • Go To Pinpoint Test C .

Seams you lack the knowledge and test equipment to tackle this type of repair . Your best bet mite be to have a qualified repair shop check it out.
So, without testing i couldn't even begin to suggest what mite be wrong . I would only be guessing , as would anyone on here would.

1993 mercedes benz 400 sel. I have no brake lights they went out about 3 days ago i check the fuses n bulb but they still dont work and my doors will no longer look with remote i check the batteries in the...


You may have two separate issues here. First as for the brake lights not working I'm guessing they all went out at once. If so there is stop lamp switch located on the arm of the brake pedal. If this switch stopped working then you will not have any brake lights. The panel underneath the dash has to be pulled out in order to see the switch. As for the locks not working the pnuematic pump which supplies vacuum for the central locking to work may have either quit working or shut down due to a vacuum leak in one of the vacuum elements. To check this go to the fuse panel in the trunk and look for the fuse for central locking and remove it for a few seconds and re insert. This will reset the pump and allow it to work again. Try the locks a few times to see if they are working. If they don't work right away then you may have a bad vacuum pump for the central locking. The central locking pump is located under the rear seat cushion on the passenger side. Hope this info helps you out if not let me know and I will try to do what I can to assist you.
