Under the dash is a flasher unit. Replace it and everything should start working again. The flasher unit is very inexpensive and available at most parts stores.

SOURCE: Hazard lights flashing

I have a 97 subaru outback and encountered the same problem. It is a security device on all newer subaru's. After changing or charging the battery, leave the negetive battery cable disconnected. Turn the key to the "on" position, then reconnect the negative terminal. This will stop the flashing.

SOURCE: won't start after cleaning battery terminals

Sounds like you have an aftermarket alarm with starter disable. By disconnecting the battery the alarm reset and the defualt setting is usually to set the alarm automatically (active arming). You have three options..
A. If you have the key fob that went with the alarm you can disarm the alarm.
B. If no key fob is available you can disconnect the battery again, turn the ignition key to the on position and reconnect the battery. This usually doesn't allow the alarm to set and allows the car to start.
C. Remove the aftermarket alarm system. This is usually the long term fix i recommend if the fob isn't available. Option B should get you going though.

Car battery went flat an tried jump starting an didn't work put another battery in an now wont start an hazard light an all other lights are flashing


Battery went dead or replaced, it set the alarm. Some alarms can be reset with the key, some with a scanner, some at the dealer. Year, make , and model would be helpful.

My hazards flash once I lock my car without the alarm sound. battery has been replaced on key. how can I stop this from happening?


Stop what from happening exactly? the hazards from flashing? or the alarm sound from NOT happening?

I'll go with the alarm, cuz at least that makes sense. In this case it is likely that the speaker for the alarm has broken or shorted. Check the fuse, and the speaker if you can locate it.

Hi, I have Mercedes C180, I have changed both Sam units. Now it's battery keep draining out. Once it's starts its run fine. Can some one help me please.


Don't you have some warning lights on your dash? MB cars are fly-by-wire that tend to depend so much on battery electricity when shut off. Use a high amps battery or battery recommended matching your car model. Check on some instruments that can be a parasitic drain to your car like, car alarm, sticking relays on auxiliary fans, radios. Worse you have a short somewhere or a wiring harness issue, but it should be giving you a warning on the dash.

Remote goes off continueouslly and unless battery cable remove won't stop. Also, vechicle won't start.


Some Jeep models have the ability to reset the alarm by following this procedure. Connect the battery cables and allow the antitheft alarm to trigger (usually horn honking and lights flashing). Use your ignition key to lock, unlock, lock and unlock the passenger front door. This should reset the system to be used normally. If your key fob is the problem, remove batteries to stop alarm trigger and have dealership test and/or replace fob. Hope this helps.

P reg merc c180. red light flashes on rear view mirror when drivi


If you have a small odd shaped key on the keyring there is a socket under the steering wheel (in the plastic housing) which mine fitted. By turning the key left or right in the socket it resets the light. I found that the flashing light indicated that the alarm had been triggered at some time when I had been away from the car and had switched itself off after a time. If you have this key you could try that.

How to reset the anti theft swith and Where is it


Some possible solutions that might help: 1. I'm not sure if this model comes with a Master Ignition key (which is usually a different colour fob or shape). If it does, then try starting the car with the Master key, it should override and reset the antitheft system and allow the car to start. 2. The Alarm keyfob (if it has one) battery may need replacing. 3. There may be an override key operated switch on the alarm itself or secreted away somewhere inside the car, which you can use to activate/deactivate the antitheft device? 4. You may have to key a code number onto a set of buttons on the dashboard to reset the Antitheft device? 5. Do you have the User Manual for the vehicle. There should be some explanation in there about what precautions to take when replacing the vehicle battery, and how to reset the anti theft device so that the engine can be started again
