Locks and keys, explained

Should you rekey or replace your locks?

If the lock works well and you want different keys to open it, rekeying may be enough. If the hardware is damaged, unreliable or missing a feature you need, repair or replacement deserves a closer look.

The useful question is what needs to change: who can get in, how the door works, or both?

Rekeying changes the key that works

Rekeying changes a compatible lock's internal key setting while keeping the existing hardware. Once properly rekeyed and checked, the previous key no longer operates that cylinder.

That can make sense after a move, a lost key or a change in who should have access. Getting the keys from the previous occupant doesn't tell you how many copies exist. You can change access without replacing a working handle and deadbolt just for the sake of it.

A sticking lock needs its own diagnosis

Rekeying isn't a general repair for a key that catches or a bolt that won't move. A worn cylinder may need replacement. A door that has shifted may need its fit corrected. These are different problems, even when they feel similar at the key.

If the lock works with the door open but struggles when it's closed, mention that. Buying new hardware won't necessarily fix a bolt that rubs against the frame.

Replacement can change more than access

New hardware may be appropriate when parts are damaged or you want a different handle, finish or way to enter. Moving to a keypad or smart lock is a separate choice from changing a mechanical key.

A replacement still needs to suit the door. The existing holes, door thickness and condition of the frame affect which hardware will fit. For an apartment or shared entrance, involve whoever manages that door before choosing changes.

Can several doors use one key?

Often, compatible locks can be keyed alike. That means one key operates several locks, such as a front and back door. It doesn't mean every lock can accept the same key; the cylinder and keyway need to be compatible.

Include every entrance you want covered. Changing your apartment lock doesn't change a shared lobby lock, and a separate garage or side door may still use its old key.

Is rekeying cheaper than replacing locks?

It can be, because you keep usable hardware, but it isn't always the lower total. The number and type of cylinders, condition of the locks, labor and any visit charge all affect the comparison.

Compare estimates for the same result: each lock included, the number of new keys, any repairs and the installed cost of replacement hardware. A low price for one cylinder tells you little about the whole job. Preebro can discuss the scope once the locks and access changes are clear.

A few useful questions

How much does it cost to rekey a lock?

There isn't one price for every lock. The cylinder type, number of locks, condition and visit charges affect the total. Ask for an estimate that includes the new keys and any repair work.

Do I have to replace the locks after moving?

Not necessarily. Rekeying suitable, working locks can stop the previous keys from opening them. Damaged hardware or a change in features may make replacement more appropriate.

Can all my door locks use the same key?

Compatible cylinders can often be keyed alike. Different keyways or lock systems may prevent that, so check compatibility before buying replacement hardware.

Keep what works. Change what needs changing.
