Repair
Work on the existing fault, if the assembly and available parts make that practical.

Before replacing the whole thing.
A handle comes loose. The key catches. A bolt only moves if you lean on the door. Those small details are worth keeping in the conversation.
You do not need to know whether the fault is in the cylinder, latch, handle or door. Explain what happens in normal use and what has changed.
A key that catches with the door open gives different information from a bolt that becomes difficult only when the door is shut. The hardware and the way the door meets its frame both need consideration.
Lock repair in Altadena starts with that particular entrance. Another lock fitted into the same poorly aligned opening may leave the original problem untouched.
A mortise lock sits in a pocket in the door edge. It is a different arrangement from many newer bored-door locksets, so a similar-looking handle is not enough to establish a replacement fit.
There may be a repair to the existing assembly, a compatible replacement body or a broader conversion to another type of hardware. These choices can have different effects on the door and its visible trim.
Mention any handle or plate you hope to retain. Suitable parts, condition and door preparation determine what is practical. An old lock does not automatically need to go, but age alone is not a promise that it can be restored.
Work on the existing fault, if the assembly and available parts make that practical.
A replacement still has to match the preparation, operation and other retained components.
Changing the hardware type can involve changes to the door. Ask what will be altered before agreeing.
A repaired lock can still be operated by the same keys. If your concern also includes earlier copies, ask about rekeying suitable cylinders as part of the agreed scope.
Likewise, a new key arrangement does not repair a worn handle or change a shifted door. Giving each task a clear purpose makes the proposal easier to assess.
On an Altadena home or workplace, include the person who can approve changes to the entrance. For a broader household request, see residential locksmith help.
Not automatically. Dimensions, preparation, hardware function and retained trim need checking before a part is chosen.
Keep the hardware in place. If it is safe, views of the door faces and edge can help show the original arrangement without dismantling it.
