"Absolutely fantastic Emergency Locksmith Service from American Locksmith LLC! I accidentally left my keys in the ignition, and the locksmith arrived faster than I could finish my coffee. Quick, efficient, and friendly service. I hope I don't lock myself out again, but if I do, American Locksmith LLC is my go-to."

"Rory knows his business! The latch bolt had seized up in the strike plate because the antique wooden door had swollen with all the rain and was wedged within the door frame so tightly that it was impossible to open. Rory knew right where to place the tip of a screwdriver to pop that old door right open! It was like magic! Heâ s my hero! If you need a real professional locksmith, give Arvada Lock and Key a call and ask for Rory!"

Locksmiths questions, answered by experts

If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.

Yes, locksmiths can design and install master key systems that grant different levels of access to various employees while maintaining overall security.

A door lock service is performed by a professional locksmith, and the cost of hiring a locksmith for these kinds of repair tasks usually runs in the $100 to $250 range. It all depends on the type of locks you have, how many locks are included in the service, and where your home is located. Always choose reliable, trustworthy locksmiths, and get a few quotes before making your choice. 

Many local hardware stores have the equipment to copy basic keys at a low cost. Some locations may have freestanding machines where you can pick out a blank and insert it and your original key into the duplicating machine.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.
