"Jacob from Your Neighborhood Locksmith was great with communication. He was prompt to contact me and schedule service. He communicated frequently to provide updates on his ETA. He arrived on time and completed the initial project within an hour and without damaging the door. He was courteous, efficient and flexible, willingly fixing another lock for me when asked. Would definitely work with Jacob from Your Neighborhood Locksmith again."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"We hired Bob on the strong recommendation of some friends who have used him for years, and he did a variety of handyman projects for us: snaked cable through a wall, hung mirrors, installed pegboards, repaired an exterior door, installed bathroom towel bars, etc. Bob performed all tasks very professionally in a reasonable amount of time, and we were very satisfied with the results."

"Joseph Sweeney did an excellent job repairing three doors in my home. One of the doors was completely off the hinges, and the other two needed new doorknobs and adjustments so they would open and close properly. He got all three doors working perfectly again, was professional, efficient, and made sure everything was done right. I?m very happy with the work and would definitely recommend Joseph to anyone who needs handyman or door repair work. 5 stars!"

Locksmiths FAQs, answered by experts

The benefit of deadbolt locks is that they're much harder to force open than simple locks with pin tumbler mechanisms, so they may offer added security. This feature is why many locksmiths recommend deadbolts for home security. For many households, this added protection and peace of mind is well worth the cost of installing a deadbolt.

When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy. When it’s all said and done, you can have a new key in your hand in just a couple of minutes.

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

Typically, it can take around 15 minutes to rekey a lock. The time depends on the type of lock and how skilled you are at rekeying. The first time you rekey a lock, it may take a little longer. Once you get the hang of the process, it will move along much more quickly.

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.
