Replacing Worn Hardware and Enhancing Home Protection

Residential deadbolts and commercial entry locks experience continuous friction, leading to internal component wear. Over time, keyways loosen, pins wear down, and latches fail to retract smoothly, making the lock vulnerable to bypass. When relocating to a new residential property or commercial space, changing the locks is necessary to ensure that old keys in circulation cannot gain access to your premises. Professional lock replacement provides a fresh security threshold, securing your entry points with modern hardware.

At GTA Lockman, we handle lock installations, rekeying, and upgrades. Our mobile service vans are equipped with residential deadbolts, handle sets, commercial mortise cylinders, and electronic smart locks from leading brands. We install new hardware with precise door preparation, ensuring the lock housing fits flush and the bolt engages the strike plate pocket securely.

Lock Wear Failures

Common Door Lock Issues

Difficulty Turning the Key

Bent internal cylinder pins or dirt accumulation makes the key hard to turn. We clean the housing or replace the cylinder plug to restore function.

Environmental Corrosion

Outdoor exposure rusts latch bolts and springs, causing the lock mechanism to freeze. We replace weather-worn hardware with outdoor-rated locks.

Strike Plate Misalignment

Door sag shifts the deadbolt latch out of alignment with the frame strike, preventing the bolt from locking. We adjust and enlarge the strike keeper.

Professional Lock Fitting & Security Realignment

A new lock must fit the door preparation perfectly. Gaps or loose mounting plates weaken the lock assembly, making it vulnerable to prying or hammer attacks. Our locksmiths perform precise wood and metal door preparation, ensuring cylinders sit flush and latch bolts retract cleanly. We carry a wide selection of commercial and residential hardware in our mobile vans, allowing us to change your locks and cut extra duplicate keys on site.

We provide flat-rate lock changes and security upgrades across the Greater Toronto Area. All hardware and installations are backed by our 90-day parts and labour warranty. Estimates are provided on-site before any installation begins.

Flat-Rate Billing

No hidden charges; all installation costs are quoted upfront.

90-Day Warranty

Clean Preparations

All deadbolts are fitted flush for clean lines and maximum strength.

Extra Keys Cut

We duplicate additional keys on-site for professional use.

Comprehensive Security Protocol & On-Site Assessments

Our lock change protocol focuses on physical security and hardware longevity. We evaluate the door frame condition, reinforce the strike plate with 3-inch screws to anchor it deep into the wall stud, and verify that the deadbolt has a full 1-inch throw to resist crowbar attacks. If we are installing smart locks or electronic keypad deadbolts, we verify that the lock bolt enters the frame strike pocket smoothly without friction, which preserves battery life and ensures consistent locking. These security standards guarantee that your home or office thresholds are protected against unauthorized entry.

We also check cylinder tolerances and align handle set latches to prevent latch binding, ensuring the door opens and closes with ease.

What Our Customers Say

Lock Replacement Specialists FAQ

Lock Change & Security Installation Services FAQs

Rekeying involves changing the internal pins of your existing lock cylinder so that a new key works while old keys are disabled. Changing the lock means removing the entire hardware housing from the door and installing a brand-new lock assembly, including the latch and cylinder.
You should change your locks if you have recently moved into a new property, lost your keys, experienced an attempted break-in, or if the lock is rusted and difficult to turn even after lubrication.
Yes, we replace mortise cylinders and hook-bolt locks standard on aluminum-framed glass storefront doors. We can also key these cylinders to match your existing commercial master key system.
Yes, we supply and install electronic keypad locks and smart locks from leading brands. We ensure the door prep matches the lock requirements and program your entry codes on-site.
We service and install locks from major brands including Medeco, Mul-T-Lock, Schlage, Yale, Kwikset, Baldwin, and Corbin Russwin, ensuring high-quality hardware for every application.

Panic Bar & Exit Devices

Safe exit egress requirements dictate that public buildings feature crash bars on exit routes. We install and service push-pad exit bars, vertical rod panic devices, and alarms. Proper adjustment ensures the door unlatches with minimal pressure during evacuation.

Hydraulic Door Closers

A leaking or slamming door closer is a hazard that can damage frames and cause injury. We replace worn hydraulic cylinders, calibrate closing speeds, and adjust backcheck cushioning. Correct regulation keeps the door closing smoothly without slamming.

Security Plates & Latch Guards

Exposed latches are vulnerable to prying, shimming, and crowbar attacks. We install heavy steel latch protectors, cylinder guards, and frame reinforcement plates. These physical barriers shield the lock latch and discourage break-in attempts.

High-Security Lock Cylinders

Upgrading to restricted key systems prevents unauthorized duplication. We install drill-resistant mortise cylinders, patent-protected keys, and high-security locks like Mul-T-Lock Interactive+ or Classic Pro. This guarantees key control and threshold protection.
