How to Compare Lock Rekeying with Lock Replacement

Tell the locksmith whether a key is lost, copied, damaged, a lock is sticking or access needs to change after a tenant or contractor leaves. Identify which doors and access devices are involved, who owns or manages the property and whether there is an urgent security issue.

Do not publish key codes, addresses or other security-sensitive details.

Ask whether the proposal changes the internal keying, lock cylinder, full hardware or another component, and whether existing keys will still work. Have the locksmith explain compatibility with the door, frame, access system, fire-door requirements or building rules. Do not attempt to dismantle or alter the lock yourself.

Check the locksmith’s identity and any licence, registration or credential required in the property’s state or territory. Request the call-out, parts, labour, after-hours fee, warranty and any extra work in writing before authorising it. Requirements and consumer protections vary; use the relevant local regulator or advice service if unclear.

Renters should contact the owner or property manager before arranging a lock change except where an urgent legal or safety situation requires immediate assistance. Keep written approval and agree who receives new keys. NSW renters can start with NSW Government renting guidance; other jurisdictions have separate rules.

A locksmith handles locks and access hardware; a cleaning provider does not rekey, replace, test or certify locks. If an authorised service leaves ordinary surface debris, any later cleaning is a separate task and quote.
