1 keypad button does not work

I have a DSC PC5010.



One of the buttons on the keypad is not working. I want to change the code. How do I change the alarm panel code?

Which button isn't working? You may or may not need it to change the code.

Thank you.
It's one of the buttons used to activate/deactivate the alarm. I'd like to be able to change the code.

Programming the Master Code

To program the Master Code, enter [✱][5][current Master Code][40][new Master Code]. The Master Code must be four digits unless otherwise indicated by your installer. Enter digits 0 through 9 only. Press [#] to return to the Ready state.

If one (or more) of the keypad buttons is becoming non-responsive, a quick fix that may fix it is to power the system down (no you won't lose any programming, you will just need to set the time and date), then open the keypad and clean the dark patches on the backs of the keys, and the contact points on the circuit board with a cotton swab _lightly_ moistened with denatured alcohol.

Over time, skin oils and general grime build up on those contact points, and a cleaning may buy you some time before you _have_ to replace the keypad.

Can a DSC PC-1500 keypad be opened to clean contacts? How?

On many of them, if you remove the face from the base plate, the membrane with the keys comes off with the face, exposing the backs of the keys, and the contact points on the circuit board. Not all do, and it's been long enough for a PC1500, that I don't rightly remember.

Sorry for bumping a slightly old thread but I confirm that its possible to clean PC1500rk membrane contacts for keypad. After removing keypad from wall, you have little plastic clip on the bottom which holds circuit board in place. Just carefully bend it while pulling circuit board out from the faceplate. Clean both circuit board and membrane with alcohol. You can even replace membrane with newer generation PC1555 keypads, or even replace whole faceplate if its really worn out, just led descriptions wont match but it will fit just fine. Done that myself, but opposite way (took membrane from pc1500rk and installed it onto pc1555 keypad with worn membrane).

I actually used Isopropyl (rubbing) alcohol. Worked like a charm! Cleaned both keypads and now they both work perfectly. The hardest part was getting the keypads off the backplates.

Thanks guys.
