Lock rekeying is the process of altering the internal tumblers of an existing cylinder so that it operates with a new key while rendering old keys useless. During a rekeying service, our technician removes the cylinder plug, extracts the old key pins, and inserts new pins that match a different key cuts depth. This is a cost-effective solution when you want to change access permissions without replacing decorative brass trim or functional lock bodies. Conversely, lock cylinder replacement involves removing the entire mechanical assembly—including the cylinder housing, tailpiece, and plug—and installing brand-new hardware. Replacement is necessary when the existing lock body is worn out, corroded, or damaged beyond repair, or when you wish to upgrade to high-security restricted keyways.
The American National Standards Institute (ANSI) collaborates with the Builders Hardware Manufacturers Association (BHMA) to classify residential and commercial locks based on performance, durability, and strength. Grade 1 represents the highest level of residential and commercial security. To verify if your deadbolt meets Grade 1 standards, inspect the lock body for a stamped certification mark. Grade 1 deadbolts are engineered to withstand up to 10 hammer strikes, resist bolt prying up to 150 foot-pounds, and complete 250,000 operational cycles. They feature a solid steel bolt with a full 1-inch throw and a hardened steel roller insert to resist sawing attacks. Standard residential locks are typically Grade 3, which only require 100,000 cycles and minimal impact resistance.
Yes. Many modern smart locks utilize standard mechanical cylinder plugs that can be rekeyed to match your existing physical keys. This is particularly useful if you want to maintain a single key profile across all exterior doors while adding smart access capabilities to primary entryways. However, compatibility depends on the keyway profile of your existing keys (typically Kwikset KW1 or Schlage SC1). Our technicians can examine your hardware, identify the keyway profile, and determine if the new smart lock can be keyed to match your home's master key system. If the profiles are incompatible, we can rebuild the cylinders of your other doors to match the new smart lock keyway.
If a key breaks off inside a lock cylinder, do not attempt to force the remaining portion of the key into the lock or turn the cylinder plug with a screwdriver. This will push the broken fragment deeper into the plug, damaging the internal pins and springs and making extraction much more difficult. Leave the lock untouched and contact a professional locksmith. Our mobile units carry specialized key extraction tools, including hook extractors and spiral extractors. We insert these tools along the keyway profile, hook the teeth of the broken key blade, and pull the fragment out without damaging the lock. Once extracted, we can cut a replacement key on-site using the broken fragments as a template.
A commercial master key system organizes access permissions across a facility using a structured hierarchy of keys and cylinders. The system utilizes pins with multiple shear lines, allowing a single cylinder to be operated by different key profiles. The hierarchy starts with the Great Grand Master Key, which operates all locks across multiple facilities. Below this is the Grand Master Key, which opens all locks in a single building. The Master Key operates locks within a specific department or department sub-group, while the User Key only opens a single cylinder (e.g., an individual office). This system allows business managers to control access permissions while minimizing the number of keys required by managers and tenants.
Patented, restricted keyways are critical for business security because they prevent unauthorized key duplication. Standard commercial keys can be copied at any hardware store or automated kiosk without verification. Conversely, restricted keys utilize patented keyway profiles that can only be sourced from authorized locksmith partners. The blanks are not distributed to the public, and duplicating a key requires presenting the authorized signature card. This gives business managers absolute key control, ensuring that employees cannot make unauthorized copies of keys to the facility. Additionally, high-security restricted cylinders feature anti-picking pins and hardened steel inserts to resist physical attacks.
Panic bars and exit devices are designed to facilitate safe egress from a building during an emergency. Local building codes and NFPA 101 Life Safety Regulations mandate that exit doors in high-occupancy facilities must be equipped with single-motion latch release devices. This means that a person can open the door simply by pushing against the horizontal panic bar, without requiring any key rotation, turning motions, or special knowledge. Our commercial locksmiths ensure panic devices are installed correctly, adjust latch alignment, and verify that the door swings freely when the bar is depressed. We also install fire-rated panic hardware that functions as a secure door lock during normal operations while guaranteeing immediate release during fire events.
Commercial door closers control the closing speed and latching force of heavy doors, ensuring they close securely without slamming. In high-traffic environments, door closers should be inspected annually and adjusted as weather changes affect the hydraulic fluid viscosity. Signs that a closer needs repair or replacement include hydraulic fluid leaking from the cylinder body, the door closing too fast (slamming) or too slow (failing to latch), or visible alignment issues. A slamming door poses a safety risk to visitors and places strain on the door frame and hinges, while a door that fails to latch compromises security and HVAC efficiency. We adjust closing speeds, latching speeds, and backcheck resistance, or replace worn closers with heavy-duty commercial units.
Yes. Our mobile automotive locksmith units are equipped with advanced programming computers that connect directly to your vehicle's OBD-II diagnostic port. We program transponder keys, proximity smart fobs, and remote keyless entry systems on-site, saving you the expense and hassle of towing your vehicle to the dealership. We generate fresh electronic key codes, delete lost keys from the vehicle's memory to prevent unauthorized access, and cut mechanical emergency key inserts. We maintain a large inventory of OEM and high-quality aftermarket keys for a wide range of domestic and import vehicle models, completing most programming services in a single visit.
When a car key operates the door locks but fails to rotate the ignition cylinder, the issue is typically caused by worn internal components. Automotive keys and ignition locks are subject to thousands of operations, causing the key cuts to wear down and the internal brass split-tumblers (wafers) to bend or warp. Because the ignition lock requires much tighter tolerances than door lock cylinders, a slightly worn key or bent wafer will prevent the cylinder from rotating. Another common cause is a failing steering wheel lock assembly that has locked the ignition. Our technicians resolve ignition issues on-site by removing the ignition lock cylinder, replacing worn wafers, and cutting a new key to match the factory specifications.
High-quality aftermarket automotive key fobs are just as secure as OEM factory-programmed keys, provided they are programmed correctly by a certified automotive locksmith. The security of a smart key fob is determined by the encryption protocol and rolling code algorithm used to communicate with the vehicle's immobilizer system. We use premium aftermarket key fobs that match the exact transponder frequency and encryption standards of the factory keys. During programming, we synchronize the fob's electronic chip with the vehicle's ECU using secure diagnostic protocols, ensuring the rolling code matches and preventing relay attacks or key cloning.
Laser-cut keys, also known as sidewinder or high-security keys, feature a thick blade with a constant depth track milled down the center of the key, rather than notched cuts along the outer edges. This design makes the key blade significantly stronger and less prone to snapping. Mechanically, laser-cut ignition cylinders utilize split-wafers that slide along the central track, requiring tighter manufacturing tolerances and providing superior resistance to lock picking. Additionally, laser-cut keys are symmetrical, allowing them to be inserted into the ignition in either direction. Cutting these keys requires a specialized CNC key cutting machine, which our mobile units carry to duplicate and replace keys on-site.
