Lock Rekeying
Trusted Lock Rekeying in Oakland County, Howell, and Holly, MI
Rekeying is one of the most practical things a homeowner can do after moving into a new house, losing a key, or handing out a copy to someone who no longer needs access. It gives you full control over who holds a working key without touching the door hardware itself. LKE Locksmith provides professional rekey service for homeowners across Holly, Oakland County, Howell, and the surrounding Michigan area. We come to you, work with your existing locks, and have most jobs finished in a single visit.
What Is Lock Rekeying and How Does It Work?
When our locksmiths rekey your locks, they replace the pins in the internal lock cylinder with pins that match the cuts in a new key. This renders all old keys useless and instantly improves your home's security.
Every door lock has a cylinder, which is the round piece the key slides into. Inside that cylinder is a set of small pins, each cut to a specific height. When the right key is inserted, it pushes each pin to the exact height needed to allow the cylinder to rotate and open the lock. Rekeying means removing those pins and replacing them with a new set that matches a different key. The lock body stays on the door. Only the internal pins change.
The rekeying process requires disassembling the lock cylinder, removing the old pins, inserting new pins sized to a new key, and reassembling everything. The result is that your old key no longer works, and a new key does. It is the same lock, same hardware, same finish, reconfigured to a key that only you have. This is also how a locksmith can rekey multiple locks in your home so they all open with the same key, which is useful if your doors currently have mismatched hardware from different brands.
When Does Rekeying Make Sense?
Rekeying is the right call in any situation where the concern is access control rather than the condition of the lock itself. The most common reasons homeowners reach out for rekey service include:
- Moving into a new home where previous owners, contractors, or real estate agents may still have copies of the existing key
- Lost or stolen keys where you cannot confirm the key is gone for good
- Changing access after a tenant, house cleaner, contractor, or anyone else who had a key no longer should
- Wanting all the deadbolts and door locks in your home to work from a single key rather than carrying several
- Upgrading security after a break-in where the point of entry was a door with an intact lock
In each of these cases, the existing hardware is still functional. Rekeying lets you protect your home and your family without the cost of full lock replacement. Most homeowners are surprised at how quickly the job gets done. A locksmith with the right tools can typically rekey a standard deadbolt in a few minutes per lock.
Rekeying vs. Replacing Your Locks
If the hardware is in good working order, rekeying is almost always the better option. It costs less, takes less time, and leaves your existing door hardware in place. Replacing locks makes more sense when the cylinder is worn, the mechanism is damaged, the lock is difficult to operate even with the correct key, or the existing hardware is builder-grade and not worth preserving.
One customer called us after moving into a home where three deadbolts were rusted, one had been installed upside down, and none were worth saving. Rekeying was not the right answer there. Full replacement was. We swapped everything out, corrected the installation, and left two spare keys at no extra charge. If you are not sure which direction makes sense for your situation, we will assess the condition of your current locks and give you a straight answer before any work begins. Our lock installation and repair page and lock replacement page cover those options in more detail.
Can You Rekey a Lock Yourself?
DIY rekeying kits are available at most hardware stores, and they do work under the right conditions. The main requirement is that all the locks you want to rekey are the same brand, since pins and key plugs are not interchangeable across different brands. You also need the current working key for each lock, the correct rekeying kit for that specific brand, and a fair amount of patience. The process involves disassembling the cylinder, keeping track of small pins that are easy to lose, and reassembling everything in the correct order.
For a single lock on a door with matching hardware and a working key, a confident and handy homeowner can manage it. Where DIY rekeying tends to fall apart is when locks are from different brands, the current key is missing, or the cylinder has any wear that makes disassembly tricky. A damaged pin or a cylinder that will not reassemble cleanly can turn a straightforward job into a lockout situation. A locksmith brings the right tools for any lock type, is not limited by brand, and can rekey your entire home in the time it would take to work through one lock with a kit. It is also worth noting that rekeying applies to traditional mechanical locks. If you have electronic or smart locks, those use a different access control method. Our smart lock installation page covers what those options look like.

Lock Rekeying FAQs
What is lock rekeying?
Lock rekeying is a way to change which key works in a door lock without replacing the whole lock. A locksmith adjusts the lock cylinder so the old key no longer works and a new key operates the lock.
When should I rekey locks instead of doing lock replacement?
Rekeying is often the better option when your current locks are in good condition, but you need to control access after a move, a staff change, or lost keys. Lock replacement (or new lock installation) may make more sense if the lock is damaged, worn out, or you want a hardware upgrade.
Can you make multiple locks work with the same key?
Often, yes. We can frequently rekey locks so multiple doors use the same key, as long as the locks are compatible. This is common for deadbolts and knobs, and it can reduce the number of keys you carry while keeping security tight.
What happens during the rekeying process?
The rekeying process involves changing the pin setup inside the cylinder. The process involves changing the pin sizes so the key cuts match, which means installing new pins and removing the old pins. This is done inside the key plug (also called the plug or cylinder plug) of the lock.
Can I rekey a lock myself with a rekeying kit?
Some handy homeowners try DIY rekeying using a rekey kit or rekeying kit, but it can be time consuming and easy to get wrong without the right tools. A small mistake can cause a lock to jam or reduce security. A professional rekey service helps ensure the lock operates smoothly and stays secure.
Do all lock types and brands allow rekeying?
Not always. Some lock types, different brands, and certain electronic locks do not rekey the same way, and compatibility matters if you want one key across multiple doors. Locks that are the same brand and keyway are typically easier to match with identical keys.
Can rekeying be used with a master key system?
Yes. Rekeying is commonly part of building or maintaining a master key system for businesses. We can set up cylinders so certain keys open specific doors while a master key provides broader access, depending on your access plan.
How much does lock rekeying cost, and what affects the service fee?
The cost and service fee depend on how many locks are being rekeyed, the type of cylinders, and whether you want all doors keyed alike. Rekeying can save money compared to replacing multiple locks, while still protecting your home, family, and belongings with controlled access.
