The moment you close on a new home in Greenwich, assume that between 3 and 10 people have a working key to your front door.
Rekeying is the fastest fix: we swap the pins inside your existing lock so old keys stop working. It takes about 10 minutes per door.
Replace the lock entirely if the hardware is corroded, if you're upgrading to a smart lock, or if you want a higher security grade like Medeco or Mul-T-Lock.
