"Citywide Roadside Lock and Key did an excellent job installing a new lock to our residential front door and provided three sets of keys for access. They were professionally, courteous., and knowledgeable.The house is an older property that belonged to our late grandfather and grandmother who passed on. The front door was very old. However, the Lock Smith asked for a picture of the lock, which I sent and he knew exactly what type of lock it was that needed to be replaced. Prompt in getting us scheduled to complete the job.

"I am unable to rate their quality of work, as we did not have anything done. My husband had called the company to get a quote to come out and rekey a vehicle. He did not set up an appointment. The gentleman showed up and insisted that he was here for a scheduled appointment. I called my husband and had him on the phone explaining to the man that he never scheduled for him to come out, he was only getting prices and that company had a higher price so he decided not to call them back and schedule. The man insisted and began to get threatening with me. I had to close the door on him as he was screaming at me. I told him he needed to leave or I was calling police. Beware, this man was not pleasant to deal with and the company gets your address even if you are just asking for a price (so they can quote according to how far away you are). He was nasty."

Locksmiths questions, answered by experts

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.

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.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

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.
