What locks do locksmiths recommend for an exterior door?

For most exterior doors, a deadbolt is a sensible starting point. It extends a solid bolt into the door frame, while a knob or lever lock usually relies on a spring latch. A deadbolt paired with a suitable entry lock gives you a separate way to secure the door.

The lock is only part of the setup. The door, frame, latch, and strike plate all need to be in good condition and work together. A strong lock on a loose or damaged door may not perform as intended, so look at the complete opening before choosing hardware.

For a home, choose a lock you can operate reliably and that fits the door. A business may need a different arrangement if staff share access or the entrance needs to work with a broader access plan.

Which lock type fits the way you use the door?

Should you rekey a working lock or replace it?

Rekeying changes which key operates a compatible lock while leaving the existing lock hardware in place. It can suit a lock that works properly when you want old keys to stop working, such as after a move or when you are unsure who still has a copy. Learn more about our lock rekeying service.

Replacing the lock makes more sense when the hardware is damaged, unreliable, does not fit the door, or lacks a feature you need. If the key sticks, the bolt drags, or the lock feels loose, first check whether the door is aligned; the problem may not be the lock itself.

If you are deciding how to rekey locks or how to change a lock, start by identifying the problem you need to solve. A locksmith can check the lock’s condition and compatibility before recommending whether to keep the existing hardware or replace it.

How can you choose a lock that fits your door?

1. Decide what the lock needs to do — Write down whether you need exterior security, shared entry, keypad access, or interior privacy. Check that the option you are considering addresses that specific need.
2. Identify the door — Note whether the door is an exterior or interior door and whether it is wood, metal, or another material. Check the door label or existing lock paperwork if available, and make sure the proposed lock is intended for that door.
3. Check the door’s condition — Open and close the door, then look for sagging, cracks, or movement around the frame. If the door shifts or will not close cleanly, resolve that issue before choosing hardware.
4. Look at the lock arrangement — See whether the door has a deadbolt, a keyed knob or lever, or both. Check that each part operates without sticking; a new lock may not solve a door-alignment problem.
5. Consider who needs access — Count the household members, staff, or other authorized users who need keys or codes. Choose a system you can manage, and check that you can remove access when circumstances change.
6. Decide whether electronic access is practical — If you are considering a smart lock, check its door requirements and how it handles backup access. Make sure the people who use the door can operate it and know what to do if its electronic features are unavailable.
7. Compare the lock’s intended use — Read the product information for the door type and use the lock is made for. Check the packaging or instructions for compatibility details before buying.
8. Confirm the door locks correctly — After the lock is fitted, close the door and test the key, thumb turn, or keypad from the proper side. Check that the latch and deadbolt move freely and that the door stays shut without forcing it.

What should you check before selecting door hardware?

• The frame and strike plate — Look for looseness, damage, or a bolt that misses its opening. A locksmith can assess whether the frame or strike plate needs attention along with the lock.
• The lock’s condition — Notice whether the key turns smoothly, the thumb turn moves freely, and the lock stays secure in the door. Sticking or looseness can point to wear, a fit issue, or door alignment.
• The number of keys in circulation — If you cannot account for every key, consider rekeying a compatible working lock. If the hardware is damaged or unsuitable, ask about replacement instead.
• Your access preferences — Decide whether you prefer a traditional key, shared keys, or keypad access. Choose an arrangement that is manageable for everyone who is authorized to use the door.

What should renters and shared households consider?

If you rent, ask your landlord or property manager before rekeying or replacing a lock. They can tell you what changes are allowed and how keys or access must be handled. Do not remove or alter a lock without permission.

In a shared home or business, agree on who should have keys or codes before changing access. Make a plan for updating access when someone no longer needs it, and consider whether a single lock or a broader access system best fits the door and the people using it.

What problems mean the lock or door needs attention?

• The key catches or will not turn — Do not force it. Check whether the door is pressing against the frame; if the key still sticks, have the lock examined before it fails completely.
• The bolt does not line up — If the deadbolt hits the frame or will not extend fully, the door may have shifted or the hardware may not fit. Avoid relying on a lock that does not secure consistently.
• The lock or door moves in place — A loose lock, damaged door, or shifting frame can affect how the lock functions. Have the full assembly checked instead of assuming that replacing only the lock will fix it.
• A new lock does not operate smoothly — Stop and check the product instructions and fit. If the latch or deadbolt binds, contact a locksmith rather than forcing the lock or making repeated adjustments.

When should you call a locksmith about a new lock?

Call a locksmith if you cannot identify a compatible lock, the door or frame is damaged, or the lock does not work reliably. Professional help is also useful when you want to rekey several compatible locks or coordinate access for a household or business.

A locksmith can assess the door and existing hardware, explain whether rekeying or replacement fits your situation, and check that the finished lock operates correctly. To reach MD Locksmith, use our contact page, or visit MD Locksmith in Silver Spring for service information.
