Just moved in? Rekey before you unpack

Kill prior owner or tenant keys — same locks, new control

Moving into a Dallas home or apartment? Prior keys may still exist. Rekeying is the fast way to make sure only you (and people you choose) can enter — same deadbolts and knobs, new keys, usually same day. Landlords: rekey between tenants. Offices: rekey after employee turnover.

Call (469) 750-0855 to schedule residential or commercial rekey.

What rekeying is (and when it beats replacement)

Same cylinders, new pins — old keys stop working

Lock rekeying is a cost-effective security reset: instead of buying new locks, we re-pin the cylinders you already have so old keys stop working. It’s a strong fit after a move, when keys go missing, or when you need organized key control for a rental or office.

Rekey vs replace

  • Rekey when the lock body is still solid and you only need new keys / kill old ones.
  • Replace / install when the lock is damaged, outdated, or you want a different lock type (smart lock, higher-security deadbolt). Related: lock installation, lock change, lock repair.
