"I contacted Doorbusters Lock & Key for rekeying several locks at my home, and they were excellent from start to finish. The technician arrived quickly, was professional and polite, and rekeyed everything perfectly. All the locks work smoothly, and the price was fair and exactly as quoted. I really appreciate how efficient and honest they were, definitely a company I’ll call again for any locksmith needs. Highly recommended!"

"Despite a hiccup with scheduling, AA Lock & Key was professional, cost-efficient, and great to do business with. I had the pleasure of working with the owner, who even went above and beyond the call of duty by helping me a door that was jamming when we tried to close it. He kept me abreast of everything he was doing, made me test his work while he was there, and all-in-all proved that the hiring of AA Lock & Key was a good decision. Should we need a locksmith in the future, I will be hiring them."

"Wonderful. Returned my call shortly after I reached out through Angie's List, came out that same day (a Sunday no less!), and had the work completed with in short amount of time. Replacing a door knob and dead bolt sounds like an easy proposition, but this really wasn't. I had tried and failed several times finding hardware that would work in the undersized holes and decided I needed to use a professional. Good decision."

Locksmiths questions, answered by experts

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.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security. 

Door locks should be changed roughly every seven years. The average lifespan of a door lock is seven to 10 years, so it’s best to err on the side of caution and change them early, especially if they are showing signs of wear and tear. Examples of deterioration include visible rust and difficulty opening or closing the door. Some locks can work safely beyond 10 years, but it depends on how often they are used and whether they are exposed to damaging environmental conditions like precipitation or extreme temperatures.
