Electronic Alarms and Home Security Devices - Bad keys on alarm keypad ?

Some keys are not working to make electrical contact on Napco Magnum RP2000LCD kepad.
The unit is about twelve years old with a lot of use for certain digits.
Is there a replacement kepad that can be inserted into the unit without having to replace the entire unit or must I replace the entire unit ?

If the unit has to be replaced, is it a simple replacement or is reprograming needed ?

Thanks.

Sometimes a gunked up keypad can be taken apart and carefully cleaned with something like electrical contact cleaning spray/solution. Generally, this only buys you a little time as human skin oils are actually pretty corrosive in the long run.

I don't know Napco systems well. Some things depend on the panel the keypad is attached to. What you most likely would have to redo would be things like the zone descriptors which are actually stored in the keypad's memory on some models. As long as you power the system down before replacing the keypad, there should be minimal resetting involved.

You should be able to get an RP2000LCD keypad fairly easily.
However, expect to pay a few bucks - looks like they run $150 plus.

Good luck!

Thanks for your comments.

One suggestion was to buy a new keypad - approx. $150.

I powered down the system and opened the keypads on each floor (only the pad on the
1st floor didn't seem to work on certain keys where the same number code was used repeatedly. All other keys worked fine. The silicone rubber keypad came out easily. I cleaned the plastic film, a circuit which is direcly behind the keypad with a Q-tip. I could see the "dirt" that was removed- perhaps carbon that had broken away from the plastic fim circuit over 12 years.
The problem keypad worked fine however I switched the plastic film circuit in the 1st floor with the one used on the 2nd floor.

I would think the plastic film circuit would be something one could purchase separately as a repair item but a supplier would prefer you purchase a new kepad. I will persue the possibility of a repair kit that would be common to several Napco keypads.

Thanks again for your suggestion.

I have a brand new Napco RP-2000lcd keypad in a sealed package if anyone is interested *** *** ****

Well, it has been 3.5 years, I hope the op has taken care of this by now.;)
