Mailbox Lock Repair Tips | Avoid the Crown Lock
Mr. Locksmith Automotive (604) 259-7617
When it comes to mailbox locks, there’s one golden rule: never attempt to work on the Canada Post Crown lock. Crown locks, commonly found on older Abloy mailboxes, are the main access locks used by postal workers to open the entire top and bottom of each mailbox unit. These are strictly for authorized postal personnel, and tampering with them is prohibited.
As a licensed locksmith, our focus is on individual mailbox keys and locks, not the mailperson’s main access. We can repair, replace, or rekey mailbox locks, including holding screws and tail pieces, ensuring that your mailbox works smoothly without compromising postal security.
Step-by-Step Mailbox Lock Replacement
-
Drill the shear line: For older locks, drilling at the shear line is a straightforward method to open the lock for maintenance. Always use the correct drill bit for precision.
-
Remove the C-clip or nut: Most locks have a small C-clip securing the tail piece; some models may use a tiny nut. Loosen carefully to avoid damage.
-
Detach the tail piece: Twist and remove the tail piece to access the internal components.
-
Match and install new tail pieces: Our mailbox lock kits come with multiple tail pieces for various brands. Always use new components to prevent wear or jamming.
-
Reassemble carefully: Replace the lock washer and nut, snugging them just enough to hold the mechanism in place. Over-tightening can jam the lock.
-
Clip on the new lock: Once assembled, the lock snaps in securely, ready for use.
