Rekeying swaps the internal pin configuration of a lock cylinder so a new key is required and the old key no longer works. It is commonly used when a homeowner moves in, after a tenant leaves, or when keys are lost or misplaced. Rekeying preserves the existing lock hardware in most cases, which makes it a cost-effective alternative to full replacement when the lock mechanism is in good condition. You can choose to have multiple locks keyed alike so one key operates several doors, or to have separate keys for each lock if you prefer. Not every lock can be rekeyed; some advanced or damaged cylinders need replacement instead and the technician will point that out during the on-site assessment. We carry a selection of cores and key blanks used commonly in residential properties so most jobs are completed with existing hardware. If a lock is corroded, stripped, or of an incompatible type, the technician will explain replacement options and keep you informed so you can decide how to proceed.
What affects the cost
Several factors affect the quote for a rekey job and we discuss those on the phone before any work starts. Expect the final quote to reflect the number and condition of locks and whether any cylinders need replacement instead of rekeying.
- Number of locks involved
- Condition of existing cylinders
- Need for keyed-alike setup
- Type of keys or blanks required
- Any required lock replacements
Worth knowing before you call
A common misconception is that rekeying will fix a damaged lock. Rekeying only changes the pinning so different keys work; it does not repair broken mechanisms. If a lock is loose, jammed, or shows corrosion, replacement may be the safer choice. Many homeowners ask whether rekeying is enough after a break-in; rekeying prevents the same keys from opening your doors, but you should also check strike plates, door alignment and any other entry points that may have been compromised. When you want one key for several doors, make a list of every lock you want included before the visit so the technician can plan. Keep in mind that some specialty locks and older mortise cylinders may require parts that are not on the truck; in those cases we explain options and return with the correct components if you approve. Finally, never hand an unknown caller a key code or grant access without seeing identification; verify the person you call and confirm the phone quote before work starts.
Before we arrive
A little preparation helps the visit go smoothly and keeps the focus on the work itself. Gather any keys you have for the locks and note which doors you want keyed alike or kept separate.
- Locate current keys and set aside duplicates
- Decide which doors need one key versus separate keys
- Clear access to doors and remove pets from the work area
- Have proof of residency or ownership ready if requested

Questions from Trainer customers
These are the questions people ask most before booking this service. If your Trainer question isn't here, call us — we'll answer it directly.
Can you rekey every lock in my Trainer home?
Most standard residential cylinders in Trainer homes can be rekeyed, and we assess that on site. If a cylinder is damaged, corroded, or a specialty model, the technician will explain whether replacement is necessary and present options before proceeding.
Will rekeying in Trainer stop old keys immediately?
Yes. Once the technician changes the cylinder pinning and tests the new key, previously cut keys that matched the old pins will no longer operate the lock. The change is immediate after we confirm the new key works.
How do I decide which locks to have keyed alike in Trainer?
Consider which doors you use most often and whether you want one key for convenience versus separate keys for added security. Many Trainer homeowners key the front door, garage entry and basement door alike while keeping bedroom or office locks on different keys.
Do you provide new keys in Trainer after rekeying?
Yes, the technician provides the new keys needed to operate the rekeyed locks and tests them on site. If you need extra copies, let us know during the phone consult so the tech arrives with enough blanks.
What if my locks are old or unique?
Older or nonstandard locks may require special parts or a full cylinder replacement. The technician identifies any such locks during the assessment and explains the trade-offs so you can choose replacement or rekey-compatible upgrades.
