Needed a second key fob for my truck after losing the spare. Bought a blank fob online and the programming couldn’t have been easier: done in my driveway in about 10 minutes. On time, professional service and a fair price. Highly recommended

How much does a locksmith cost?
You get an upfront price before we start any work. The price depends on the service and the lock or vehicle. Call or send us a message for a quote.
Can you replace a lost car key or program a key fob at my location?
Yes. We make and program car keys and key fobs at your location for a wide range of makes and models, even if you have no key left. Call or send us a message with your vehicle's year, make and model and we'll tell you what we can do.
What is rekeying and how does it work?
A rekey changes the existing combination of a cylinder or lock so that the current keys stop working and new keys operate it. The hardware stays the same. It is cheaper and faster than replacing the entire lock and is often used when moving into a new home or after losing keys.
Should I change the locks when I buy a new home?
You don't need to replace the locks—rekeying is faster and more affordable. We change the combination or reconfigure your locks so current keys no longer work, and you get brand new keys. This prevents previous owners, contractors, realtors, or anyone else with old keys from accessing your home. If your locks are in good condition, rekeying costs a fraction of full replacement and provides the same security benefit.
When should I replace or rekey my locks?
Replace or rekey your locks if: they're sticking, jamming, or not locking properly; you've just purchased a new home; you've lost your keys; you've experienced a break-in; a roommate or employee has left; or you've given out keys to contractors, cleaners, or service workers. Rekeying is usually the best option unless your locks are damaged or you want to upgrade to smart locks.
