Does any body know how to reset the ML350 alarm??....The remote control doesn't work after i replaced a new battery to the remote control. I couldn't even use the remote to lock/unlock the car. I was

Has to be done with a scanner. Some times it can't be done. You would have to get a body control module and have it programmed.

what is the alarm make and model ? check in your drivers pack the alarm manual may have been put in there when it was installed , all alarms will be different so do need to know the make etc

Well when you replaced the battery did anything else on the key fob work? Often times you have to reprogram the remote in order for it to function properly. Try getting inside the vehicle and manually lock all doors with the driver's side switch. Put the master key in the ignition switch and turn the switch to the run position but do not start it. Now push and hold the lock and unlock buttons at the same time until the locks make noise....may take 10 to 30 seconds. After you have the key fob programmed, see if the alarm will turn off with the remote. Did it work? The only way to totally turn off the alarm is with a GM Tech @ or 3 scan tool and go into body control bidirectional controlling procedures or with a very good aftermarket scanner with good bi-directional functionality.
The alarm works via the body control module on this vehicle and i am thinking it uses the PK2 system and if you do not have a properly coded key or the BCM is loosing memory, then check for any and every blown fuse and replace as needed.to start with.. If the vehicle stays running after starting then the bcm/key is reading correctly.

might need the body control reset.

Take it back to the body shop an have them reset everything . Nothing you can do .

Have you replaced the Batteries in the remote control??? Does your vehicle require a "smart" key???

I would try disconnecting the battery for five minutes like resetting a computer. Replace the battery in key fob. Body computer does strange things with lights hope it doesn't need to be replaced about 350 dollars if you have it replaced and any thing else doesn't work after they replace it tell them. I had two of them replaced for me because they are rebuilt

Hello,

The new battery should have reactivated the alarm? If this is a keyless entry, than your original code should work?

If it doesn't than you need to call the dealer, or seervice provider for your alarm system there has to be a reset code, or a new one has to be provided?

I would try your normal code first! If it works, your good, if not, your going to be on the phone! No body but the place you purchased your vehicle from or the Alarm system provider can give you that answer!

Kind Regards!

I know this sounds obvious, but did you run your battery dead? If you don't know, get the battery checked.as for as tuning off the alarm... Just simply disconnect your negative battery cable. This will reset the alarm. This doesn't solve the problem but makes it less annoying while figuring it out. What about the battery in your remote, is it dead? Look for any wires from the alarm that may be frayed, cut, or corroded. Hope this helps.

O.k. this is a security feature of your alarm the car now essentially thinks that it is being stolen. In order to fix this issue you need to reset the alarm buy reconnecting the battery and using your electronic alarm sensor if you have one (if this doesn't work get new battery for alarm sensor)
