The Von Duprin on the back door won't latch on the second push. The Sargent 80 push pad bent after a delivery driver hit it with a hand truck. The dogged-down crash bar is stuck and won't release. Most of the time we repair the bar for $140-380 instead of replacing the whole device at $480-980. New install is a separate service - this page is for fixing what you already have.
Crash bar repair in Port St. Lucie - Von Duprin 33A, 88, 98, 99 series, Sargent 80 series, Adams Rite 8000 series. Repair the failing component (spring, latch, push pad, dogging cam) rather than replace the whole device.
Cost: $140-380 typical repair. $480-980 if the whole bar needs to be swapped (we have new device install priced separately at /services/panic-bar-installation-port-st-lucie-fl/).
Repair preserves your fire-marshal-approved install - no permit, no re-inspection trigger, same hardware brand maintained.
The push bar drops at one end. The latch will not catch in the strike. The dogging key turns but the bar will not stay depressed. Or the worst version - the bar pushes but the door does not open, and now a Tradition Square employee is locked inside after closing. Existing Detex, Von Duprin, and Sargent panic devices fail in predictable patterns and almost all of them rebuild rather than replace.
A door company will tell you the whole bar needs to come off and a new one needs to go on at $700-plus. Nine times out of ten the actual repair is a $35 latch kit, a $20 dogging cylinder, or a rim strike that worked loose and needs to be templated back into position. Crash bar repair runs $140-320 and the bar you already own keeps working.
Doctor Lockout carries Detex, Von Duprin, and Sargent rebuild kits on the van. Call (772) 284-5142 - dispatcher in PSL answers, no call center.
Detex Value-Series latch kits, Von Duprin 99/22 latch kits, dogging cylinders for hex and key dogging - on the truck.
Rebuild on existing hardware is half to a third the cost of a full panic-bar swap, and the door is back in service today.
End-of-day lockup failures get rolled before close. PSL Boulevard and Tradition Square plazas covered after hours.
Most 'will not latch' problems are strike misalignment, not bar failure. We template the strike at no extra charge.
Bent or dented touch bars get swapped without replacing the chassis. Cost stays in the repair range, not the replace range.
Multi-location panic-bar service across a PSL retail portfolio billed to one account, one invoice cycle.
Door companies replace. We repair. They quote you a new $700 panic bar because that is what they sell and install. Doctor Lockout opens the chassis, identifies the worn part, and rebuilds it - usually inside 90 minutes on-site.
Honest assessment of whether the chassis is salvageable. Most are. Some are not - and we tell you which is which.
Hex dogging, key dogging, electric dogging - three different failure modes, three different fixes. We know which is which on sight.
Existing Grade 1 panic gets Grade 1 rebuild parts. We do not save $40 by mixing grades on a high-traffic egress door.
After repair we verify operating force, latch projection, and dogging behavior. Same checks the fire marshal runs.
Commercial crash bars get hit, kicked, leaned on, and cycled 50-2,000 times per day. After 5-15 years of hard service, the predictable failures show up:
Latch failure - won't latch on the second push. The latch retracts when the bar is pushed but doesn't extend back out fully on release. The latch return spring has weakened or broken. Or the latch itself is worn from years of misaligned strike contact. Repair: $140-260 for new spring and latch assembly. Common on Von Duprin 33A and Sargent 80 series.
Dogging mechanism stuck. Dogging is the feature that holds the bar in the depressed position so the door stays unlatched during business hours. When the dogging cam sticks, the bar feels permanently loose or won't release. Repair: $180-280 to free or replace the dogging cam.
Broken push pad / actuator. The pad is bent or cracked from impact - delivery truck, hand truck, kicked open by an angry tenant. The internal bar mechanism is fine; the cosmetic / structural push pad assembly needs replacement. Repair: $220-380 depending on series.
Broken spring. One or more internal springs (lever return, latch return, dogging) has snapped. Standard rebuild kit replacement: $140-260.
Bent / damaged bar. The horizontal push bar has been bent by impact. On Von Duprin 88 / 98 / 99 and Sargent 80, the bar is replaceable as a single component without changing the end housings. Repair: $260-380.
Mounting screw failure / loose chassis. The end-housings have worked loose from the door over time. The bar moves vertically when pushed. Repair: $140-220 to remount with longer screws / thread-lock and re-square the chassis.
End cap or trim damage. Cosmetic damage to the lever, trim plate, or end cap. Replacement parts: $80-180 plus install.
The four lines we keep parts for:
Von Duprin 33A. The light-duty surface-mount Von Duprin, common on PSL Boulevard plazas and older Tradition Square retail. Latch springs, dogging cams, and end-cap kits stocked. Most 33A repairs $140-260.
Von Duprin 88 / 98 / 99. The heavy commercial Von Duprin lines - found on St Lucie County schools, government buildings, hospitals, and most newer PSL commercial. 99 series is the highest grade. Latches, springs, dogging cams, and replacement bars stocked for 88 and 99. Most 88 / 99 repairs $180-380.
Sargent 80 series. 8800 surface mount and 8700 concealed vertical rod. Specified on many St Lucie government and school buildings. Latches, springs, dogging stocked.
Adams Rite 8000 series. For aluminum-storefront doors - Tradition Square, the PGA Plaza, Riverwalk Center, plazas along US-1. The 8000 series has its own internal architecture (designed around narrow stiles). Latches and spring kits stocked.
Specialty / older / less-common (Yale 7000, Detex - covered on the separate Detex page, Precision, Falcon) often need parts ordered in - typical 2-5 day lead. We diagnose on-site and quote both the order-in repair and the full replacement so you can pick.

Call (772) 284-5142Most common cause: the latch return spring inside the end housing has weakened or broken. The latch retracts when the bar is pushed (this is the egress action and still works), but doesn't fully extend back out to engage the strike on release. Diagnostic is fast - we push the bar, watch the latch extend, and measure the throw. Fix: new latch assembly with new spring, $140-260 on Von Duprin 33A or Sargent 80 series. Less commonly: the strike has drifted out of alignment, in which case the strike position is moved and the latch is fine.
Dogging is the feature that holds the bar in the depressed (open / unlatched) position. Used during business hours so the door swings freely both ways without the panic-bar latch engaging. Most commercial bars dog with a hex key. When the dogging cam inside the end housing sticks - usually from wear, corrosion, or a bent dogging shaft - the bar stays loose and the latch won't re-engage. Fix: open the end housing, free or replace the dogging cam, $180-280 typical.
Roughly 75% of the Von Duprin 33A / 88 / 99 service calls we run are repair candidates - one latch, one spring kit, one dogging cam, one push pad. Repair $140-380 versus full device replacement $480-980. Replacement makes sense when: the bar itself has been severely bent, the chassis casting has cracked, the end housings have multiple failures simultaneously, or the device is older than 20 years and the entire mechanism is worn beyond rebuild. We tell you on-site which path is right.
Latch repair: $140-260. Dogging repair: $180-280. Push pad replacement: $220-380. Multi-component spring kit rebuild: $180-320. Bent-bar replacement: $260-380. Full mounting re-secure: $140-220. Most jobs come in at $180-280 total. Hardware at MSRP, no markup.
Yes for any restaurant with occupancy over 50 (the threshold for outward-swinging single-action egress under FFPC 7th Ed and NFPA 101). Most full-service restaurants in PSL exceed that threshold easily. The requirement is single-action egress hardware on every door in a path of egress - not specifically a 'panic bar' by name, but a panic bar (or panic device, or fire exit hardware) is the standard way to satisfy the requirement. Bar / quick-service / drive-through restaurants under 50 occupants may be able to use simpler hardware but most still install a panic bar for liability and code-future-proofing reasons.
Generally no - repair of existing fire-rated egress hardware on an existing certificate of occupancy doesn't trigger a new inspection. Major changes (replacing a non-rated bar with a different brand / model, changing the function class, adding electrified components) sometimes do. We tell you upfront if your specific job is repair (no inspection trigger) versus replacement (possible inspection). Full replacement to a different brand often triggers inspection on schools, hospitals, and assembly occupancy buildings.
Crash bar service calls run across the same PSL commercial map as the mortise lock work - Tradition Square retail, PGA Plaza, Riverwalk Center, the US-1 corridor between Walton Road and St Lucie West Boulevard, the PSL Boulevard strip, the office plazas along St Lucie West, schools (Treasure Coast HS, Centennial HS), hotels, and the restaurant clusters along US-1 and Crosstown Parkway.
