"Very well, the locksmith arrived n time and got to work right away in replacing the locking system. He then took the time to show me how to adjust the door in the future so it would not stick as the house moved. An absolute must if you need a locksmith."

Locksmiths FAQs, answered by experts

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.
