I have problems with alarm charges

Hello, I am Nuebo in this forum, I have a Citroen Xsara Coupe of the year 2000, with an alarm it charges and today it does not let me turn it off with the controls, and changed the batteries and remain without working, the alarm does not have specturrientes, so I could circulate with the car, but it is triggered with the movements detector. You can help me '

Hello, my advice is that you disable the alarm with the key that goes on the siren, and look at another type of alarm.
I know that the advice does not tell you anything, but the experience I have with those alarms, ends up replacing it, because it costs more to repair than set up a new brand.
I wish I could help you.
All the best.

Well, first of all, thanks for trying to help me, the truth is that the problem is already solved, it was a deconization of the control signal, which is solved by pressing the two buttons that this control has at the same time until the red lez of the command is fixed, which flashes when you press the control to turn off and turn on the alarm, then press only the button of large (the one to turn off) Synchronized command. This concrete cobra alarm has no key, or I don't have it (the car is second hand), but I know what you mean, and calling installation workshops, they told me that or they no longer work with Cobra or take the car, the solution I found it in another Internet forum, one of caranas, I think .., but I said thanks anyway.
