Start with the door, not the product photo.
A new lock needs to suit the door it will be installed in. Door thickness, existing openings, frame condition and the space around the handle all matter. A product that looks right online may not fit without extra work.
Explain whether you are replacing existing hardware or adding a lock where there is none. Photos of both faces and the door edge can help describe the starting point. An older opening may need a different approach from a straightforward replacement.
Think about daily use.
Consider who uses the door, whether they need separate keys or codes, and what happens when the door closes. A private home entrance, rental unit and shared building entrance have different permission and access needs.
For a keypad or smart lock, check physical fit, power requirements and the manufacturer’s compatibility information. Some features require an app, hub or network. Confirm who manages the device and what access method is available if a battery runs low or a connection is unavailable.
Agree on the complete installation scope.
Clarify whether you are supplying the lock or discussing suitable options. Ask what the estimate covers: removal, fitting, any necessary preparation, parts and setup. Cosmetic marks from old hardware may remain unless refinishing is separately included.
Tenants and businesses in managed properties should get permission before replacing hardware. Any change to a shared, fire-rated or required exit door must preserve its required function. Describe those conditions before work is arranged, then test the agreed locking and entry functions once the installation is complete.
Before you call
- Door type and existing hardware
- Who has approved the change
- Keys, codes and everyday access needs
A useful question
Can a keypad be fitted without replacing my entire door?
It may be possible if a suitable model fits the door and existing preparation. Photos help start the discussion, but hardware compatibility and door condition must be checked. Do not assume every keypad uses the same openings.
