Frequently Asked Questions

Rekeying replaces the pins inside your existing lock so old keys no longer work, while changing locks means installing completely new hardware. Rekeying costs less and works when locks are in good condition but you need to invalidate old keys after moving or losing keys.

Yes, locksmiths can create keys by decoding the lock cylinder or using the VIN for vehicles. The process involves disassembling the lock to read pin depths or accessing manufacturer key codes. This works for house locks, car keys, and most commercial hardware.

Locksmiths use slim jims, long reach tools, or air wedges that access the door mechanism without scratching paint or breaking glass. The method depends on your vehicle's make, model, and lock type. Newer cars with electronic systems require different tools than older mechanical locks.

Don't try to force the broken piece deeper by inserting another key or tool. Locksmiths extract broken keys using specialized hook tools and tweezers designed to grip metal fragments. Attempting removal yourself often pushes the piece further in, making professional extraction harder.

Smart locks eliminate key-related vulnerabilities like bumping or picking but introduce electronic risks like hacking or battery failure. Traditional deadbolts resist digital attacks but remain vulnerable to physical manipulation. Security depends on installation quality, model selection, and whether you prioritize physical or digital threat protection.

"Do not duplicate" markings have no legal enforcement for locksmiths - they're warnings, not legal restrictions. True key control requires patented keyways or restricted key systems that require authorization codes. Standard keys with duplication warnings can be copied unless backed by registered security systems.

Master key systems let one key open multiple locks while individual keys work only on specific doors. Businesses use them when different employees need access to different areas but managers need full building access. The system requires specialized pin configurations in each lock cylinder.

Rekey after employee terminations, lost master keys, or every 2-3 years when employee turnover is high. Frequent rekeying prevents unauthorized access from former employees who may have kept keys. Businesses with high-security needs or valuable inventory should rekey more frequently.

Most doors accept upgraded locks if the backset and door thickness match standard measurements. Locksmiths can install high-security cylinders, smart locks, or commercial-grade deadbolts into existing door prep. Only unusual door thicknesses or custom sizes require new doors or modification.

Dirt, metal shavings from key wear, and dried lubricant build up inside the cylinder, making pins stick. Outdoor locks corrode from moisture exposure, and misaligned strike plates from door settling create resistance. Regular cleaning and graphite lubricant prevent most failures without replacement.
