I’m looking for a rfid activated deadbolt lock for my door. Thing is, everything I’ve found requires a new door, as my door has 3 deadbolts activated by the one lock cylinder system thingy.
I don’t fully know what type, but if anyone can help suggest anything. And preferably something that’ll work both with keys and chips
Your best option would be to talk to a locksmith. You are looking for a multi point locking system. They might have to install a commercial system for this.
Which country is this in? (Different countries have different common locking systems)
Can you post a picture of your door lock, I have an idea 
, but I need to see what we’re dealing with first.
