I was wondering if it’s possible to replace a faulty Videx keypad rather than the whole intercom as just 2 of the buttons which are part of the code have worn down over time 

 

It’s a GSM model as the customer tells me it calls their mobile phone 

 

I’ve attached a photo for reference and any help greatly appreciated 

 

I can go there and remove the keypad if an exact model number is needed to look up a suitable replacement 

Manual looks like this one

Possible replacement using the newer model as this one appears obsolete

2 gates, main one on the left and the other on the right 

 

There are 2 antennas that receive fob inputs

It's  just a stand alone keypad, same thing for 20 years or more,

 

The design changes, but all work the same

Thanks mate looks like I can just replace the keypad with the latest model 

Yeah just get the unit only and it will clip in.
