Changing locks is the most direct way to control access to your property. If you lost keys, there is no way to know who may find them. When moving to a new house or office, previous owners, tenants, or service providers could still have copies. Lock Change Fullerton helps you reset access so only approved keys work.
Stolen keys increase risk even more, especially if they were taken with identifying information. In those situations, replacing the lock is usually safer than waiting. Burglary repair often requires lock replacement because cylinders, latches, or strikes can be damaged internally. Even if the lock turns, it may not protect the door properly. A new lock restores both safety and confidence.
Security upgrades are also common when locks are old or low grade. Many doors still rely on basic knob locks or worn deadbolts that are easy to force. Upgrading to stronger deadbolts, mortise locks, or high-security cylinders improves resistance and daily reliability. New locks also eliminate issues like sticky keys or loose handles.
Lock Change Fullerton focuses on complete solutions. A quality lock needs proper installation and a solid frame to perform well. We check alignment and recommend reinforcement when needed. This approach delivers real security, not just new hardware.
Rekeying changes the internal pins of the lock so old keys no longer work. It is often the most cost-effective option when the lock hardware is still in good condition. Rekeying is common after moving or when staff changes occur. It keeps the door appearance the same while restoring control.
A lock change replaces the hardware completely. This is recommended when the lock is damaged, outdated, or when you want a different security level or style. Upgrading to a deadbolt, mortise lock, or smart lock requires replacement. Lock Change Fullerton inspects the door first and explains which option makes more sense.
Deadbolts are widely used on residential and light commercial doors. In a deadbolt system, the cylinder is built outside of the door frame and the bolt extends into the frame when locked. With a reinforced strike, deadbolts resist forced entry well. They are popular for front and side doors.
Mortise locks are installed inside a pocket cut into the door. This design spreads force across a larger section of the door, making it ideal for heavy or high-traffic use. Mortise locks are common on storefronts, offices, and older solid wood doors. They combine latch and deadbolt functions in one lock body.
The right choice depends on door construction and usage. Residential doors usually perform well with quality deadbolts. Commercial and heavy doors often benefit from mortise hardware. Door alignment and frame strength are just as important as the lock itself.
Lock Change Fullerton helps you choose based on your actual door, not assumptions. We verify fit and operation before installation. The result is smooth locking and dependable security.
Smart locks reduce key problems and give you more control over access. Codes can be created for family members, guests, or employees without copying keys. Many smart locks allow temporary or scheduled access, which is useful for rentals and service providers. Lock Change Fullerton installs smart locks for homes and businesses.
Standard smart locks replace the full lock or deadbolt with an electronic unit. Retrofit smart locks add smart features while keeping some existing hardware when possible. Retrofit options are useful when door appearance or prep is a concern. We explain which option fits your door.
Proper alignment is critical for smart lock reliability. A misaligned door can cause battery drain or locking issues. We inspect and adjust alignment during installation. Each smart lock is tested before we leave.
Feature selection matters. Some users want keypad-only access, others want phone control. We help you choose a lock that fits your routine and stays reliable long term.
DIY lock installation can work on perfectly aligned doors, but many doors are not perfect. Small errors can cause binding or unreliable locking. DIY work also lacks a labor warranty. Many people end up calling a professional after struggling.
Professional Lock Change Fullerton service includes correct fit, alignment, and testing. We reinforce strikes, adjust doors, and ensure smooth operation. You also receive a warranty on parts and labor. Upfront estimates keep pricing clear.
