Falcon A08552-000-00 – Frequently Asked Questions

1) What is the Falcon A08552-000-00 top pin actually used for?
It is a top pin (driver pin) for Falcon mechanical lock cylinders, sold as a genuine Falcon replacement part. It sits above the key pin in the pin stack and rides on the spring, so its job is to keep the shear line correct when a locksmith rebuilds or rekeys a worn Falcon cylinder. Buy it when you are servicing a cylinder rather than replacing the whole housing.
2) Does the Falcon universal top pin work in any Falcon cylinder, or only certain ones?
It is a universal top pin meant to be used across compatible Falcon cylinder configurations, which is why one part number covers a range of service work instead of one specific lock. It is engineered for Falcon cylinder assemblies, so treat it as a Falcon part rather than a drop-in for Schlage, BEST, or Corbin Russwin pin stacks.
3) My Falcon cylinder is sticking and the key drags. Do I need a new cylinder or just pins?
If the housing and plug are sound and the trouble is worn or damaged pins, a top pin like the A08552-000-00 lets you rebuild the pin stack and keep the existing cylinder in service. Full cylinder replacement is the route when the housing, cam, or plug itself is damaged. In that case a complete mortise or rim cylinder is the order, for example the Corbin Russwin 1000 Series 1-1/2 inch mortise cylinder with an A02 straight cam, or a Schlage 20-021 six-pin rim cylinder with a vertical tailpiece cam.
4) If a Falcon cylinder is too worn to rebuild with the A08552-000-00 top pin, what complete cylinder can go in instead?
The A08552-000-00 is a loose top pin used to rebuild the pin stack inside an existing Falcon cylinder, so it only helps when the cylinder body itself is still serviceable. When the housing is damaged, move to a complete cylinder: the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam, or the Corbin Russwin 1070 Grade 1 six-pin mortise housing in 1-1/4 inch with an A01 cloverleaf cam, cover mortise prep. For rim device prep, the Schlage 20-021 rim cylinder is six-pin with a vertical tailpiece cam and the 20-022 is the same six-pin cylinder with a horizontal tailpiece cam. Confirm cam or tailpiece orientation against the lock before ordering.
5) We rebuild cylinders with pins like the Falcon A08552-000-00 - is there an option that lets maintenance staff rekey without pinning?
Pinning with a top pin such as the A08552-000-00 requires a bench, a follower, and a pinning kit. If the goal is to let in-house staff change keying without disassembly, an interchangeable core platform does that instead: the BEST 1C standard five-pin cylinder core and the BEST 1CB 150 series interchangeable core pull with a control key, and the BEST 1CDF is a drill-resistant patented interchangeable core in seven-pin brass. On the Schlage side the 20-057 is a six-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in C keyway, 643E aged bronze. Those are a different service model, not a drop-in for loose Falcon pins.
6) Is this an OEM Falcon part or an aftermarket pin?
Genuine Falcon, sourced from Falcon's own parts line, so the pin is built to OEM spec for Falcon cylinder assemblies instead of being a generic pin kit component. That matters on a commercial rebuild where mixed-tolerance pins show up later as a key that binds.
7) What part number do I give my supplier for the Falcon universal top pin?
Order it as Falcon A08552-000-00. That is the model designation for the universal top pin, and there is a single orderable configuration, so there is no finish, length, or keyway choice to specify with it.
8) I need a whole interchangeable core, not a pin. What should I be looking at?
A single top pin will not help if what you need is a core. For interchangeable core work the BEST 1C Series standard five-pin core or the BEST Peaks 1CB 150 Series interchangeable core are complete cores, and the Schlage 20-057 six-pin FSIC rim cylinder with a convertible tailpiece cam covers full size interchangeable core rim applications. The Falcon A08552-000-00 is strictly a pin-stack component for rebuilding a cylinder you already own.
9) Will the Falcon A08552-000-00 top pin work in an aluminum storefront deadlock cylinder?
The A08552-000-00 is a Falcon cylinder component for commercial Falcon mechanical lock cylinders, so it is not the part to order against a storefront deadlock by part identity. For Adams Rite storefront work, the 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness, and the 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws are both built for the Adams Rite MS1847 deadlock and deadlatch. For a wood door, the 4026 five-pin cylinder pull is made for the Adams Rite 5017 wood door deadlock and deadlatch.
10) Instead of repinning a knob or lever cylinder, is there a universal replacement cylinder I can drop in?
The Falcon A08552-000-00 is a single top pin used to restore the pin stack in a Falcon cylinder. If the faster path is swapping the whole cylinder, Kaba Ilco makes universal-style replacements: the 1539 series key-in-knob and lever universal cylinder, the 1599 key-in-knob replacement cylinder, the 1579 knob and lever cylinder for Sargent locks, and the 1549 key-in-deadbolt cylinder. Match the cylinder to the lock brand and the tailpiece the chassis expects.
11) What looks like a substitute for the Falcon A08552-000-00 top pin but is not?
Anything described as a cylinder, core, or housing is a different class of part. The BEST 12E series dummy rim cylinder at 1-5/32 inch diameter carries no working pin stack at all, and the Corbin Russwin 3070 is a six-pin rim cylinder housing with a 1-7/8 inch tailpiece. The Emtek CY4 cylinder is sold each as a complete cylinder. None of those are loose pinning components, and none substitute for a top pin when the job is rebuilding an existing Falcon cylinder.
12) The cylinder I need to service is on a residential handleset, not a Falcon commercial lock - what fits there?
The A08552-000-00 top pin is intended for commercial Falcon mechanical lock cylinders. For handleset and deadbolt work, Medeco offers retrofit cylinders built for those chassis: the 1012040 is a six-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a five-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a five-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a five-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. Choose by the tailpiece the existing lock uses.
13) Is the A08552-000-00 pin for commercial Falcon locks or residential hardware?
Commercial. The pin is part of Falcon's commercial lock parts line and is intended for mechanical lock cylinders in commercial door hardware, the kind of servicing done in office buildings, schools, healthcare facilities, and multi-tenant residential properties.
14) Can a property manager fit this, or is it locksmith work?
This is bench work. Rebuilding a pin stack means disassembling the cylinder, keeping the pins in order, and controlling the springs, so it is intended for locksmiths and door hardware professionals servicing Falcon cylinders. A maintenance tech without cylinder tools is usually better off swapping a complete cylinder.
15) If I am standardizing a facility rather than rebuilding cylinders one at a time, what should I be ordering?
The Falcon A08552-000-00 top pin is a service item for commercial door hardware, used to keep existing Falcon cylinders running. Standardizing a building is a different purchase: the Corbin Russwin 1080 is a 1-1/2 inch six-pin LFIC mortise cylinder that fits Schlage L9000 mortise locks with an A01 cloverleaf cam, the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core in C keyway. Picking one keyway and one cylinder format across the facility is what makes a master key system practical.
