"Despite the nuance of a unique brand of smart lock, the locksmith Lev was able to discern the issue of the initial install of the smart lock. Notably, before leaving, he noted issue with the physical key mechanism and instead of leaving he took the smart lock apart again to finally solve the problem once and for all. I'm highly impressed and grateful for his kindness, patience, and attention to detail. THANK YOU LEV. "

Locksmiths questions, answered by experts

There are different types of deadbolts. The most common type is a single-cylinder deadbolt, which you may recognize on your front door. This type of lock has a keyhole on the outside and a thumb turn on the inside. A double-cylinder deadbolt has two locking mechanisms and requires a key to engage on the inside as well as the outside. 

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

Locksmiths typically recommend using a dry lubricant, such as a Teflon-based option, instead of the popular oil-based lubricants you can purchase at almost any store. Dry lubricants leave a non-stick, water-repellent coating instead of attracting more dirt and debris like an oil-based lubricant. You can find these at a hardware store; some are made explicitly for lock use.
