Locksmiths questions, answered by experts

Replacing your locks isn’t always a necessary option. You can usually save money by rekeying locks instead of replacing the hardware. You should consider rekeying the locks instead of replacing them in the following scenarios:

  • You want to upgrade your existing locks.

  • You have a lock you don’t want to replace.

  • You recently bought a home and want to change the locks.

  • You lost your key.

Begin by checking the power source, typically a battery or wired connection. Ensure the battery is installed correctly, has sufficient charge, and isn't corroded. If it's a wired lock, examine the electrical connections to confirm they are secure and free from damage. Additionally, inspect the lock's programming or settings. Confirm that user codes or access credentials are programmed correctly and that any remote control devices are paired and functional.

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.
