How to fix a faulty remote alarm button.
This depends on the type of button that you had. Mine using the button type shown below

 

Once open, it would look something like this.

 As can be seen at Burron 1, open up the clip (picture C), remove (picture B) and then you will see the connector or what so ever they call it, (picture A), this is the one that need replacement.

Where to find replacement ? Try to find any faulty old car radio or cassette player…look  disamble it and try to find the button which look similar to it…

replace it…then walla…you remote alram will work like new again…!!!

Happy DIYing !!!
