Hello, this car is in my garage and I want to leave it, but I have a problem, I cannot turn off the alarm after connecting to the battery, so I replaced the battery in the remote control with a new one, but also nothing, it never was, and I will not start the engine with the alarm. The alarm loudspeaker has been disconnected because it sometimes turns on by itself.
What is this alarm? 124 had "factory" alarm? If there is a "out of factory" alarm, there should be no problem with disconnecting it. It is a matter of knowledge and skills. Basic question: what is this alarm? Perhaps it is enough to "pair" the remote control with the control unit.
Most often, you just need to close all the doors, arm the alarm, then disarm it and open the door, another option is sitting inside, the door closed, turn on the ignition and press closing and then opening on the remote control.
Photo of the remote control may not help. It would be best to locate the switchboard and determine what the alarm is. There should be a "service button" for pairing at the switchboard. You need to define the type of alarm and then find instructions for it. Or find the control panel and disconnect the alarm. I'm afraid you won't leave this garage without knowing what the alarm is!
