Keep the lock or change it
Repair comes first when a lock only needs adjustment or a replacement part. A latch that binds against the strike may not need a new lock at all.
Rekey
Rekeying changes the pins inside a compatible cylinder so the old keys stop working. The existing lock stays on the door.
- Suitable for hardware in good condition
- New keys replace the old working keys
- Does not improve the lock's security grade
- Matching keys require compatible keyways
Replace
Replacement puts new hardware on the door when the existing lock is worn, damaged or unsuitable for the security or features you want.
- Addresses badly worn or damaged hardware
- Allows a change in style or finish
- Offers a move to a higher lock grade
- Makes a change to smart locking possible
A technician must inspect the lock, its condition and compatibility before recommending repair, rekeying or replacement.

From the first call to the final test
There is a check before entry, a price before work and a test before the technician leaves. Here is how a mobile service visit is handled.
Tell us what happened
Call for an urgent problem or send a request for planned work. Give the location, the lock or vehicle involved and whether anyone is in danger.
Review the visit details
The dispatcher quotes the service call fee and work price range, then estimates arrival based on the nearest van, traffic and time of day.
Receive the technician details
Before arrival, a text identifies the assigned technician by first name and photo and includes the service van number.
Meet the assigned locksmith
The locksmith arrives in a marked Cairn van, wearing a uniform and carrying photo identification and a current locksmith work card.
Confirm permission for the work
The technician checks your ID and your authority over the home, business, vehicle or safe before opening or changing access.
Inspect and approve the price
After inspecting the hardware, the technician presents the written price on a tablet. Drilling, cutting and replacement require separate approval.
Complete and check the repair
Once approved, the work proceeds. You test the keys, lock operation and door latching with the technician before the visit ends.
Receive the itemized invoice
The final invoice lists the service call, labor and each part separately. You can receive it on paper or by email.
What the service warranty includes
Labor, supplied hardware and vehicle keys and fobs Cairn supplied have different warranty terms. Coverage depends on the work performed and the cause of the problem.
Workmanship for 12 months
If a lock Cairn installed, repaired or rekeyed stops working correctly because of our workmanship within 12 months, we return to correct that work at no charge. This applies to faults caused by our service, not unrelated problems with the door or frame.
Hardware follows the manufacturer
Hardware Cairn supplies carries the manufacturer’s warranty. The coverage period varies by brand and hardware grade. When a supplied part qualifies for a warranty claim, Cairn handles the claim with the manufacturer.
Car keys and fobs for 90 days
Keys and fobs Cairn supplied and set up for your vehicle carry 90 days of coverage. This is separate from the workmanship warranty for lock installation, repair and rekeying.
What the warranty excludes
For hardware you provide, Cairn warrants its labor but not the product. Damage from forced entry, doors or frames that shift or swell, smart lock batteries, and Wi-Fi or app problems outside the lock are excluded. These conditions are not defects in our workmanship.
Requesting warranty service
Call Cairn and describe the original work and what has stopped working. Our office reviews the service record and arranges a return visit when the problem needs an inspection. Have your original invoice available to help identify the work.
