Safe and vault locksmith services
Locked out of your safe or changing how it opens? We service home and business safes, from failed keypads to new installations and anchoring.
- Opening methods chosen after inspection
- Combination changes, electronic locks and keypad upgrades
- Installation, anchoring and ground-level moving

Opening, repairs and installation
A safe that will not open and a safe that needs installing call for different work. We handle both, including changes to the locking mechanism.

We open safes with lost combinations, dead keypads or failed locks, then handle combination changes, repairs and electronic lock upgrades.

Proof of authority comes first
Before opening a safe or changing its lock, we verify that the person requesting service owns it or has authority to act for the owner. Have the relevant documents available for the technician to examine in person. Do not send ID copies or combinations through the website.
- Government-issued photo ID
- Proof of safe ownership or authority
- Estate documents for inherited safes
What happens at a safe-service visit
Safe work starts with identifying the problem, not choosing an opening method over the phone. Here is how a visit proceeds.
Describe the safe and problem
Tell dispatch whether the combination is lost, the keypad is dead, the lock has failed or the safe needs installation or moving.
Verify authorization
The technician checks your identification and documents establishing ownership or permission to service the safe.
Inspect the safe
We examine the locking mechanism, construction, condition and access before deciding what work is appropriate.
Review and approve the price
You receive a written price before work begins. Any drilling or replacement requires your separate approval.
Complete and check the work
After service, we check the lock's operation with you and provide an itemized invoice for the work performed.
How safe-service pricing is determined
Safe opening cannot be priced accurately from a description alone. The technician needs to see the safe before giving a final figure.
Inspection before opening
Safe opening is priced only after an on-site inspection, never by phone. The $39 service call fee applies inside the service area.
Type of lock
A mechanical dial, electronic keypad or failed locking mechanism can require different service work.
Size and construction
The safe's weight, construction and condition affect the work involved in opening, repairing or installing it.
Location and access
A safe's position and available access matter, particularly for anchoring or moving heavy units.
Full written price before work
Every charge appears on the written price before work starts. If the job changes, you approve a revised price first.
Handling and damage
Handling and damage
Many safes can be opened without damaging the locking mechanism or cabinet. That is not possible in every case. A failed lock or the safe's construction may require a small drilled opening, which is repaired afterward so the safe remains usable. We explain the proposed work before proceeding.
Moving a safe requires checking its weight and the route it must travel. Cairn moves safes weighing up to 1,000 lb at ground level. Heavier safes and moves involving stairs are referred to a safe mover.
- Many safes open without damage
- Necessary drilled openings are repaired
- Ground-level moves up to 1,000 lb

What safe ratings actually measure
Fire protection and resistance to physical attack are separate measures. Read the rating for the protection it describes.
Fire rating
A fire rating describes how long a safe's interior stays below 350°F during the rated fire exposure.
- Measures protection from heat
- Time is part of the rating
- One hour is an example rating
Burglary rating
Ratings such as RSC and TL-15 describe resistance to physical attack rather than performance during a fire.
- RSC means residential security container
- TL-15 describes resistance to attack
- Different from fire protection
A fire safe is not necessarily rated to resist attack; look for a separate rating such as RSC or TL-15.

“Our office safe had a keypad that stopped responding, and we needed to get it working again. The technician checked our authorization, inspected the lock and explained the work before giving us a written price. We knew what was being done before agreeing to it.”

Questions about safe service
These are the details worth checking before arranging an opening, lock change or safe installation.
Call (702) 000-0000All questionsCan you open my safe if I have lost the combination?
Yes, lost combinations are one of the reasons we open safes. The technician inspects the safe before choosing a method, and some openings require repair work afterward.
Can you replace a mechanical dial with an electronic keypad?
Yes, we offer upgrades from dial locks to electronic keypads. The technician examines the existing safe and lock before recommending the replacement work.
Will opening my safe damage it?
Not necessarily. Many safes open without damage, but some require a small drilled hole that is repaired so the safe keeps working. We do not promise a particular opening method before inspection.
What do I need to show if I inherited the safe?
Have your government photo ID and proof of ownership or authority over the safe ready for the technician. Estate and inherited safes also require supporting documents, which the technician checks at the visit before opening or changing the lock.
Can you move my safe upstairs?
Cairn handles safe moves up to 1,000 lb at ground level. Moves involving stairs, along with heavier safes, are referred to a safe mover.
Do you sell safes, or can I visit your showroom?
We can supply and install a safe ordered for you, but we do not operate a showroom. Our Las Vegas key and safe workshop is open by appointment only, with no walk-in counter.
Do you open bank vault doors or safe deposit boxes?
No, bank vault doors and safe deposit boxes are outside our service scope. We work on residential and commercial safes, including office, cash and deposit safes.
