Dropped my keycard... broken...

Dropped my keyless card & now it works for keyless entry but the buttons don't work.

My spare stopped working too (not the battery)

What are my options repair wise?
 
Take it apart and check the circuit board for broken connections and hope you don't damage it fully or buy a new one!

i'd try get the spare working first tho.
 
Yes provided you are extremely carful, hence why I'd do it on the fully broken one.
