How a residential locksmith call runs in Newark
- Call (888) 492-0666 and describe the door. Front door deadbolt, side gate, sliding patio door: the brand stamped on the lock face helps the technician bring matching parts.
- The dispatcher confirms the address and gives you an ETA. You hear now if an after-hours charge applies to your address.
- The technician verifies that you are authorized. Photo ID with the address, a lease or closing documents, or confirmation from the owner or property manager for a rental.
- You get a written quote before any work starts. Lockouts are opened non-destructively first; drilling is a last resort and only with your approval.
- The work is done and every key is tested in every door. Rekeyed doors are checked with the new keys and the old ones, so you know the old keys no longer work.
- You receive a receipt listing what was changed. Useful for landlords, HOA records and insurance.
Residential lock types
Most houses and condos use a short list of lock types. Knowing which one is on your door helps the dispatcher send the right parts.
- Deadbolts: the primary lock on an exterior door. ANSI/BHMA Grade 1 is the strongest residential grade; Grade 3 is builder grade.
- Knob and lever sets: the latch you turn; on their own they are not a security lock.
- Mortise locks: common in older houses and some condo buildings. The lock body sits in a pocket in the door, and parts are not interchangeable with cylindrical locks.
- Keypad and smart deadbolts: battery powered, usually with a mechanical key override. Connected models add remote locking, temporary codes and logs.
- High-security cylinders: restricted keyways that cannot be copied at a kiosk, with drill and pick resistance.
- Strike plates and reinforcement: the part most break-ins defeat. Long screws into the framing and a reinforced strike matter as much as the lock.
- Brands commonly found on homes in this area include Schlage, Kwikset, Baldwin, Yale, Emtek, Medeco and Mul-T-Lock.
