Quick Answer: When to Rekey vs Replace Locks in Plano

Rekey your locks when the existing hardware works properly but you need to invalidate old keys. Rekeying changes the internal pins so previous keys no longer operate the lock. This solution works perfectly for new homeowners, after a roommate moves out, when keys go missing, or to consolidate multiple keys into one master key system.

Replace your locks when the hardware is damaged, outdated, or incompatible with your security goals. Lock replacement becomes necessary when cylinders are broken, when you're upgrading to smart locks or high-security cylinders, when moving from knob locks to deadbolts, or when the lock mechanism fails due to wear or forced entry.

For residential properties in Plano, rekeying typically takes ten to twenty minutes per lock. Full lock replacement requires fifteen to thirty minutes per door, depending on whether new holes must be drilled or existing hardware removed. Both services are completed on-site with no need to remove doors or leave your property unsecured.

Pricing: Rekey vs Replace Locks Plano

Understanding the cost difference between rekeying and replacement helps you budget appropriately. Below are typical service ranges for Plano residential and commercial customers.

Service Type	Price Range	Notes
Rekey Traditional Lock	$10–$50 per lock	Cylinder remains; pins changed
Master Key System Setup	$120–$250	Multiple locks keyed to work with master key
Replace Standard Deadbolt	$180–$400	Includes hardware and installation
Replace Smart Lock	$250–$650+	Varies by brand (August, Schlage, Yale)
High-Security Lock (Medeco, Mul-T-Lock)	Quote required	Requires specialized equipment
Commercial Lock Replacement	Quote required	Depends on number of doors and hardware type

Final pricing depends on the number of locks, hardware brand, travel distance within the Plano service area, and time of service. Emergency after-hours work may carry additional fees. Multi-lock discounts are available when rekeying or replacing four or more locks in one visit.

Understanding the Difference: Rekeying vs Replacing Locks

Rekeying is the process of changing the internal pin configuration inside a lock cylinder so that a new key operates it while the old key becomes useless. The locksmith disassembles the cylinder, removes the existing pins, and installs a new set matched to a new key. The outer hardware—deadbolt, knob, faceplate—remains in place.

Rekeying works only when the lock cylinder is in good working condition. If the keyway is worn, the pins stick, or the cylinder turns roughly, rekeying will not solve mechanical problems. In those cases, replacement is the better option.

Lock replacement means removing the entire lock assembly and installing new hardware. This approach is necessary when the existing lock is broken, when you want different lock styles (upgrading from a passage knob to a keyed deadbolt), or when switching to a different brand or security level.

Replacement also applies when moving from traditional mechanical locks to electronic smart locks. According to ALOA Security Professionals Association, modern electronic locks provide audit trails, remote access, and temporary codes that mechanical locks cannot support.

When Rekeying Makes Sense for Your Plano Home or Business

Rekeying is the faster, more economical choice in several common situations:

New home purchase. After closing on a house in Plano, rekey all exterior doors to ensure previous owners, contractors, real estate agents, and cleaners can no longer enter. This takes less than one hour for a typical single-family home with three to five exterior locks.

Lost or stolen keys. If your keys disappear and you're unsure who has access, rekeying immediately restores security. You receive new keys while invalidating the missing set.

Tenant turnover. Landlords and property managers in Plano rely on rekeying between tenants. It's faster and cheaper than replacing every lock, especially in multi-unit buildings.

Employee termination. Businesses that issue physical keys to staff should rekey locks when employees leave. This prevents unauthorized access without the expense of new commercial-grade hardware.

Master key systems. When you want one key to open multiple doors (master key) while each door also has its own unique key, rekeying configures the cylinders to accept both. This is common in offices, schools, and apartment complexes across Plano and Richardson.

When Lock Replacement Is the Better Choice

Certain scenarios require installing new lock hardware rather than rekeying:

Damaged or worn cylinders. If the lock cylinder is bent, corroded, or won't turn smoothly, rekeying cannot fix the mechanical failure. Replacement restores full function.

Security upgrades. Moving from a basic builder-grade lock to a high-security deadbolt (Medeco, Mul-T-Lock, or ASSA ABLOY) requires replacement because these systems use proprietary keyways and hardened components that resist picking, drilling, and bumping.

Smart lock installation. Installing electronic deadbolts with Bluetooth, Wi-Fi, or Z-Wave connectivity means removing the old mechanical lock completely. Smart locks integrate with home automation systems and eliminate the need for physical keys.

Lock style changes. Replacing a knob lock with a deadbolt, or adding a second deadbolt to a door, involves drilling new holes and installing fresh strike plates. Rekeying cannot accomplish these structural changes.

Forced entry or break-in. Doors that have been kicked in or pried often have bent or fractured lock bodies. Replacement ensures the door frame and lock assembly are secure once repairs are complete.

Commercial properties in Plano sometimes require panic bars, electric strikes, or magnetic locks to meet fire codes and ADA requirements. These installations go beyond rekeying and involve coordinating with access control systems.

Automotive Lock Services: Car Door Locks, Ignitions & Transponder Keys

While residential and commercial rekeying focuses on door hardware, automotive locksmith services in Plano address car key replacement, ignition cylinder repair, and transponder programming. Modern vehicles use electronic immobilizer systems that require specialized equipment to program new keys. Call or text (945) 307-3827 when you need mobile automotive locksmith service anywhere in Plano, Frisco, or Allen.

Ignition cylinder replacement. When an ignition cylinder wears out or a key breaks off inside, replacement involves removing the steering column cover, extracting the old cylinder, and installing a new unit keyed to your door locks or programmed to a new key.

Transponder chip programming. According to National Highway Traffic Safety Administration, most vehicles manufactured after 1995 use transponder keys with embedded chips that communicate with the vehicle's engine control module. Programming these keys requires scan tools and PIN codes retrieved from the vehicle's onboard computer.

Remote-head keys and key fobs. Many vehicles combine a traditional cut key blade with a built-in remote for lock and trunk release. Replacement involves cutting the blade and programming the remote to the vehicle's receiver module.

Push-to-start smart keys. Newer cars use proximity fobs that allow you to start the engine without inserting a key. These require EEPROM reading, key learning procedures, and sometimes module reflashing to register a new fob.

When to Call a Locksmith vs the Dealership

Choose a mobile locksmith when you need same-day service at your location, want to avoid towing, or have lost all keys and the vehicle is not at a dealership. Mobile locksmiths bring key-cutting machines, programming tools, and blank keys to your driveway, office, or parking lot. Service is often faster and more convenient than the dealership because we come to your location, help avoid towing, and can complete many key replacements the same day.

Arrival time depends on technician availability, traffic, and your exact location within the Plano service area. We serve Plano, Richardson, Frisco, McKinney, Allen, The Colony, Carrollton, and surrounding cities.

Choose a dealership when your vehicle is under warranty and key replacement is covered, when you need factory documentation of key programming for lease return, or when the vehicle requires proprietary software not available to independent locksmiths. Dealerships have direct access to manufacturer databases but typically require you to tow the vehicle and wait several days for key ordering.

Frequently Asked Questions

How long does it take to rekey a lock in Plano?

Rekeying a single lock takes ten to twenty minutes. Rekeying five locks on a typical house takes about one hour including setup and testing all new keys.

Can I rekey my locks myself?

Rekeying requires specialized tools (pinning kits, plug followers) and knowledge of pin sizes. Most homeowners find professional service faster, and it includes warranty coverage if issues arise.

Do I need to replace my locks after a break-in?

If the lock body or door frame is damaged, replacement is necessary. If the lock works but you're concerned about security, upgrading to a high-security deadbolt is recommended.

Can all locks be rekeyed?

Most standard pin-tumbler locks (Kwikset, Schlage, Baldwin) can be rekeyed. Some high-security and electronic locks require replacement rather than rekeying due to proprietary keyways or electronic modules.

Rekeying one lock costs ten to fifty dollars depending on the lock type. Rekeying an entire house with five exterior locks typically ranges from fifty to two hundred dollars.

A master key system allows one key to open multiple locks while each lock also has its own unique key. This setup is popular for rental properties and offices.

Can you rekey a car door lock?
