The 5-Minute Rekey vs Replace Worksheet

Walk the property once without deciding what to buy. List the front, back, side, garage, gate, detached structure, and any door that controls meaningful access. A double-cylinder deadbolt or separate knob and deadbolt can make one door more than one cylinder.

In an older Fort Worth house, the front hardware may be one brand and the garage entry another. A recently added patio door may use a third. Compatibility affects whether one key can operate several locks, so photograph the face and edge without removing anything.

For current ranges, use the lock rekey cost guide. The worksheet prevents you from requesting a vague 'change the locks' price that means something different to every caller.

Turn each key gently with the door open, then close the door and repeat. Smooth when open but hard when closed usually points to alignment, hinge, strike, or weather-seal pressure. Rough in both positions points more toward the key, cylinder, or lock body.

Mark each opening green for smooth, yellow for unreliable, or red for damaged and unsafe. Do not force a key to finish the test. A cracked key or heavily loaded bolt can snap during what was supposed to be an inventory.

Loose trim, a shifting cylinder, a latch that misses, and a bolt that cannot extend fully belong in the condition column. Rekeying alone does not repair those symptoms.

Moving, a lost labeled key, a contractor handoff, or a household change can create a key-control problem even when every deadbolt feels perfect. That is where rekeying earns its keep.

If the only concern is a sticky side door, changing which key operates it is unlikely to help. Route the symptom to inspection and repair instead.

1. 1
   Rekey group

   Serviceable compatible cylinders with uncertain keys.

2. 2
   Repair group

   Openings with alignment, latch, fastener, or serviceable component issues.

3. 3
   Replace group

   Cracked, loose, badly worn, incompatible, or unsuitable hardware.

4. 4
   Specialist group

   Glass, frame, access-control, or carpentry work outside locksmith scope.

A sensible plan might rekey four good cylinders, repair one misaligned strike, and replace one corroded side-door lock. That is not indecision. It is matching the fix to the condition.

The residential rekeying page explains service scope. Ask the provider to quote each group separately so a replacement recommendation does not hide the cheaper rekey items.

Give each provider the same cylinder count, photos, symptoms, working-key status, and desired key plan. Ask what dispatch, labor, keys, parts, and approval rules are included. If inspection can change the price, ask which findings would do that.

Do not use this worksheet to diagnose internal damage from a photo. It is a scope tool. The technician still needs to inspect compatibility, wear, and door condition.

Keep the completed list after service. It becomes a maintenance record and makes the next lost key, move, or sticking door much easier to explain.

Add two columns after the visit: the final action and the key count. Write rekeyed, repaired, replaced, or no work, plus how many new copies were issued. Note which doors share a key without writing the property address on a loose tag. If inspection found a different cylinder family than the phone photo suggested, record that too. This turns a five-minute worksheet into a useful baseline rather than a disposable shopping list. Review the baseline when a resident, cleaner, pet sitter, contractor, or tenant no longer needs access. You may not need another whole-property job. The record can show which few cylinders were exposed. It also helps when a door begins binding months later, because you can separate a new alignment symptom from the key-control decision already completed. For a Fort Worth-area house with original and remodeled doors, expect the plan to stay mixed. Uniform appearance does not guarantee compatible cylinders, and different finishes do not prove incompatibility. Let inspection settle that question.
