"I called 911 Locksmith Services for my new home, and they easily scheduled an appointment that was convenient for me. Dylan at 911 Locksmith and Security is experienced, knowledgeable, and professional with locks and security. I wanted to replace key locks with keyless entry on three doors. I also needed to match hardware to fit my personal taste. Dylan came on time for my appointment, and was prepared with everything needed for the job. After he started the work, I asked if I could add a door lock that I had neglected to include, and Dylan had no problem making a quick run to the warehouse to pick up what I wanted, and had all three of my doors finished and secure in one afternoon. After the work was complete, he took time to make sure I understood how each secure lock works. Thank you 911 Locksmith and Security, and especially thanks to Dylan for a job done well. I would recomment 9ll Locksmith and Security to anyone who wants new locks or keyless entry installed. They are the best!"

"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

Locksmiths FAQs, answered by experts

Costs depend on lock type, service complexity, labor, emergency availability, and whether security system integration is needed.

Over time, latch components may wear out or get grimy, leading to this problem. First, check for dirt, dust, or debris in the latch mechanism to ensure smooth operation. Use an aerosol duster and lubricant to clean and loosen. You may also need to tighten the screws in the component, adjust the strike plate, or replace the lock. If none of these steps resolve the problem, consult a professional locksmith.

Smart locks offer a similar level of safety to traditional or conventional locks because they often use comparable locking mechanisms, such as deadbolts. The primary difference is the access method: smart locks use a login or code instead of a physical key, which adds convenience. While not inherently safer, some smart locks have added security features that can deter intruders, like shutting down after too many incorrect code attempts or being harder to pick. For the best security, it's recommended to combine any lock with other home safety features like motion-activated lighting, security cameras, and window and door sensors.

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. However, locksmiths can typically work around keyless entries to vehicles, so it depends on what type of keyless entry system needs opening.

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.
