Commercial Door Lock Replacement: Signs, Costs, and When You Actually Need It

Your office lock is sticking, a key broke off last month, or you just took over a building and have no idea how many copies of the keys are floating around. You’re trying to figure out if you need a full lock replacement, a rekey, or if a repair will do the job. Here’s what actually matters when it comes to commercial door locks in Dallas-Fort Worth.

What Commercial Door Lock Replacement Costs in DFW

Lock TypeTypical Replacement CostBest For
Standard Commercial Deadbolt$150-$300Small offices, interior doors
Heavy-Duty Grade 1 Deadbolt$250-$450Exterior doors, high-traffic areas
Mortise Lock System$400-$800Glass storefronts, aluminum doors
Panic Bar/Exit Device$500-$1,200Emergency exits, fire code compliance
Electronic/Keypad Lock$300-$900Access control, keyless entry

These prices include parts, labor, and installation. If you need multiple doors done or you’re switching to a master key system I’ll give you a better per-door rate.

Signs Your Commercial Lock Needs Replacement (Not Just Repair)

I’ve been doing this long enough to know when a lock is truly done. Here’s when replacement is the only real option:

  • Visible damage to the cylinder or housing cracks, broken pieces, or attempted break-in marks mean the internal mechanism is compromised
  • Keys work inconsistently sometimes they turn, sometimes they don’t, even with brand new cuts
  • The lock is outdated or no longer meets insurance requirements many commercial policies now require Grade 1 or Grade 2 locks
  • You’ve inherited a building and don’t know the key history replacement is cheaper than the risk
  • The lock has been repaired twice already at that point you’re just delaying the inevitable

If the lock just needs lubrication, a pin replacement, or the bolt is catching because the door frame shifted, that’s a repair job. I’ll tell you straight up if we can save you money by fixing it instead of replacing it.

Replacement vs. Rekey vs. Repair: What You Actually Need

Rekey (Cheapest Option)

If the lock works fine but you need to control who has access — former employees, lost keys, new ownership — rekeying changes the internal pins so old keys no longer work. Takes 15 minutes per lock. Costs $75-$150 per door.

Repair (Middle Ground)

Lock is sticking, bolt won’t fully extend, or key is hard to turn. Usually means worn pins, lack of lubrication, or a misaligned strike plate. We fix the existing hardware. Costs $100-$200 depending on what’s broken.

Replacement (When the Lock Is Done)

Physical damage, outdated lock that doesn’t meet code, or you’re upgrading to electronic access. New lock, new hardware, fresh start. Costs vary by lock type — see the table above.

Common Commercial Lock Types We Replace

Mortise Locks

Standard on glass storefronts and aluminum-frame doors. The lock body sits inside a pocket cut into the door. These are workhorses but eventually wear out from constant use.

Cylindrical Locks

Most common on hollow metal doors and wood doors. Lock body sits in two holes drilled through the door. Easier to replace than mortise locks.

Exit Devices and Panic Bars

Required on emergency exits. These get beat up from daily use. If the bar is loose, sticking, or the latch isn’t catching, replacement is usually faster than repair.

Electronic and Keypad Locks

Popular for offices that want to eliminate physical keys. If you’re upgrading from traditional locks, we install keyless entry systems across multiple doors and can tie them into access control systems.

How Long Commercial Lock Replacement Takes

For a standard commercial door, figure 30-45 minutes per lock if it’s a straightforward swap. Mortise locks take longer sometimes 60-90 minutes if the door prep needs adjustment. If you’re replacing locks on 10+ doors, I’ll schedule a dedicated block of time and work around your business hours.

Frequently Asked Questions

Can you replace a commercial lock without changing the door?

Yes, as long as the new lock fits the existing holes and door thickness. Most commercial doors use standard prep sizes.

Do commercial locks need to meet fire code?

Exit doors and doors along fire egress routes often require panic hardware or fire-rated locks. If your building has specific code requirements, I’ll make sure the replacement lock is compliant.

How long do commercial locks last?

Grade 1 commercial locks in normal use last 10-15 years. High-traffic exterior doors might need replacement sooner maybe 7-10 years. Interior office doors with light use can go 20 years.

Can you match new locks to existing keys?

Yes, if you want all your doors on the same key. We can key the new locks to match your current system or set up a master key system so you have one master that opens everything and individual keys for each door.

Will you work after hours for commercial lock replacement?

Absolutely. We’re available 6 AM to 11:45 PM daily. A lot of our commercial clients prefer us to come in early before employees arrive or after close so we’re not disrupting business.
