The buttons are a little hard to push but that my because they are new.

After key is cycled 8 times make sure you have all key pads you ant to program handy then press any button on them, doors will lock and unlock to verify that programming is finished

However the buttons are too hard to press and often times don't pick up that you're trying to press them

The old ones had lost buttons and were inoperative

The only issue I see is the buttons are a bit weak and stick in sometimes.
