Falcon A08554-000-00 – Frequently Asked Questions

1) What exactly is the Falcon A08554-000-00 and what does it do inside a lock cylinder?
A08554-000-00 is Falcon's tumbler spring, the small coil spring that sits above each pin tumbler in a Falcon mechanical lock cylinder and pushes the pin stack back down when the key is pulled. Replace them when a cylinder gets sluggish, a key binds, or a pin fails to drop after rekeying. It's a genuine Falcon service part, not a complete cylinder, so it only helps if you're rebuilding or rekeying a cylinder you already have.
2) My Falcon cylinder is worn out, not just weak on spring tension. Should I buy springs or a whole cylinder?
Springs only fix spring problems. If the plug is worn, the keyway is damaged, or you want a different keying platform, replace the cylinder instead. ZenSupply carries complete cylinders in the common commercial formats: mortise housings like the Corbin Russwin 1000 Series 1-1/2 inch with an A02 straight cam, rim cylinders such as the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal tailpiece cam), and interchangeable core options like the BEST 1C Series 5-pin core or Schlage 20-057 FSIC rim cylinder. Match the housing type and cam or tailpiece to your existing lock body before switching.
3) Is the Falcon A08554-000-00 a replacement cylinder, or just a part that goes inside one?
The Falcon A08554-000-00 is a replacement part only - tumbler springs for Falcon mechanical lock cylinders, supplied 100 to a pack, and they are useless on their own without a cylinder body to rebuild. If what you actually need is a complete cylinder, a mortise unit such as the Corbin Russwin 1000 Grade 1 series 1-1/2 inch mortise cylinder with an A02 straight cam, or a rim unit such as the Schlage Commercial 20-021 six-pin rim cylinder with a vertical tailpiece cam, is a finished assembly you install rather than a component you service with.
4) I rebuild and rekey pinned cylinders in the field - is there an option that avoids that work instead?
Rebuilding is exactly what the Falcon A08554-000-00 tumbler springs support: they restore spring tension in Falcon mechanical lock cylinders during service or rekeying, bought in bulk for high-volume benchwork. If you would rather swap hardware than pin it, interchangeable-core cylinders change the approach - the BEST 1CB 150 series interchangeable core, the BEST 1CDF drill-resistant seven-pin brass 150 series core, or the Schlage 20-057 six-pin full-size interchangeable core rim cylinder let a core come out and another go in without opening the cylinder.
5) Does the A08554-000-00 spring pack come as one spring or in bulk?
It ships as a 100-pack of tumbler springs. That quantity is aimed at locksmith bench stock and facility maintenance crews doing volume rekeying, where springs get lost or fatigued and you want a jar of them on the shelf rather than ordering per job.
6) Do these tumbler springs come with pins or a full rekey kit?
No. The A08554-000-00 is springs only, 100 of them. Bottom pins, master pins, top pins, and plugs are separate line items, so order those alongside if you are building out a rekeying bench rather than just replenishing springs.
7) Will Falcon A08554-000-00 springs service a Medeco or Adams Rite cylinder too?
The A08554-000-00 springs are genuine Falcon components engineered specifically for Falcon mechanical lock cylinder assemblies, so treat them as Falcon-only bench stock. Other makers' cylinders are serviced or replaced as their own units - for example the Medeco 1075127 five-pin rim-type lazy motion single cylinder for handlesets and deadbolts, or the Adams Rite 4036 Grade 1 mortise cylinder with five-pin security. Ordering those as complete cylinders is the path there, not a Falcon spring pack.
8) For a residential-style knob or deadbolt cylinder swap, do I need a spring pack like the Falcon A08554-000-00?
No. The Falcon A08554-000-00 tumbler springs are a commercial-duty bench part for rebuilding Falcon mechanical lock cylinders, not a drop-in cylinder. A straight swap is simpler with a prebuilt replacement cylinder such as the Kaba Ilco 1599 key-in-knob replacement cylinder, the Kaba Ilco 1549 key-in-deadbolt cylinder, or the Kaba Ilco 1579 knob and lever cylinder for Sargent, each supplied as a complete unit.
9) Are these springs suitable for commercial building maintenance or are they a residential part?
Falcon lists the A08554-000-00 tumbler springs as a commercial part, built for the cylinder function expected in commercial door hardware. They get used across office buildings, schools, hospitals, government facilities, warehouses, and multi-tenant residential portfolios where the locks themselves are commercial Falcon hardware.
10) Are these genuine Falcon parts or aftermarket springs?
Genuine Falcon, sourced through the Falcon parts program and made to the tolerances of Falcon cylinder assemblies. For facilities standardized on Falcon hardware, that matters: an off-spec spring rate is a common cause of a cylinder that keys fine on the bench and then binds in the door.
11) What parts look like an alternative to the Falcon A08554-000-00 but do a completely different job?
Cylinder pulls are the usual mix-up. The Adams Rite 4025 five-pin tumbler cylinder pull with through-screws and the Adams Rite 4024 cylinder pull with trim plate mounting are both intended for Adams Rite MS1847 deadlock and deadlatch systems, and the Adams Rite 4026 five-pin tumbler cylinder pull is for the 5017 wood door deadlock or deadlatch - those are door-face trim carrying a cylinder, not internal components. The Falcon A08554-000-00 is a 100-pack of tumbler springs that goes inside a Falcon mechanical lock cylinder during service.
12) We stock Falcon spring packs for maintenance - what should we stock alongside them for a facility standardizing keying?
The Falcon A08554-000-00 tumbler springs cover the service side, keeping installed Falcon mechanical lock cylinders working after rekeying across offices, schools, healthcare, government and multi-tenant residential buildings. For the keying program itself, core and housing stock pairs with it: the BEST 1C series standard five-pin cylinder core, the Corbin Russwin 1070 Grade 1 series 1-1/4 inch six-pin mortise housing with an A01 cloverleaf cam, and the Corbin Russwin 3070 six-pin rim cylinder housing with a 1-7/8 inch tailpiece.
