Q: What is the most secure type of lock for a house's exterior doors?

• <div><p>Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors.

Q: Can a locksmith open a keyless entry?

• <div><p>It depends on what type of keyless entry it is and if the locksmith has the proper tools to remove a keypad entry lock since some are more advanced than others.

• <div><p>There are many <a href="https://www.angi.com/articles/types-of-deadbolts.htm">types of deadbolts</a>, 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. </p></div>
