Medeco 20008S4T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20008S4 cylinder fit a Schlage B Series deadbolt?
Yes. The 20008S4 is a Key-in-Knob/Lever style retrofit cylinder built to drop into Schlage B, E, and F160 Series deadbolt locksets. You keep the existing deadbolt body, latch and strike prep and swap only the cylinder, so there is no door machining and no full lockset replacement. If your deadbolt is a different Schlage family or another brand entirely, this is the wrong cylinder number, Medeco builds over 100 cylinder and tailpiece configurations and you want the one cut for that lockset.
2) Is the Medeco 20008S4 a 5-pin or 6-pin cylinder, and does that matter for keying it into my system?
Five pins. The 20008S4 is a 5-pin cylinder, so it keys into a 5-pin Medeco system. If your building is already mastered on a 6-pin Medeco bitting, a 5-pin cylinder will not take those keys and you need the 6-pin equivalent instead. Check which pin count your existing key system runs on before you order a stack of these for a re-key.
3) Can I get the Medeco 20008S4 in M3 or Biaxial keyway to match keys we already carry?
Both. The 20008S4 is offered in Medeco Biaxial and in M3 technology, and the two are not interchangeable keyway families, so you order the one your existing key system runs on. If your facility is already on M3, order M3 and it keys into that system; if you are maintaining an older Biaxial system, order Biaxial. Getting this wrong means a cylinder that physically installs and will not accept your key.
4) What is the difference between the Pinned and Sub-Assembled versions of the Medeco 20008S4?
That axis decides who does the keying. Pinned means the cylinder ships built to a bitting. Sub-Assembled ships as an unpinned cylinder for a locksmith or an end user with a Medeco pinning kit to key on their own bench, and Sub-Assembled, No Slider omits the slider component as well. If you do not run your own pinning operation, order Pinned. If you hold your own key system and cut your own keys in house, the sub-assembled options let you key it to your existing bitting on site.
5) Is the Medeco 20008S4 UL 437 listed for drill and pick resistance?
Yes, the 20008S4 carries a UL 437 listing for drill and pick resistance. It is also certified to ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength, and ANSI/BHMA A156.5 Grade 1 for heavy-use commercial applications. That combination is what a spec on a government, healthcare or campus job usually calls for when high-security cylinders are specified by standard rather than by brand.
6) Can tenants copy a Medeco 20008S4 key at a hardware store?
No. The 20008S4 uses Medeco M4 utility patent-pending key control, which restricts unauthorized key duplication, and the cylinder is certified to ANSI A156.30 Level A specifically for patent-protected key control. That is the practical reason property managers put these on deadbolts on turnover units and mechanical rooms: keys do not walk, and a departing tenant or contractor cannot quietly have one cut at a kiosk.
7) What finishes does the Medeco 20008S4 come in to match my existing Schlage hardware?
Thirteen finishes, by BHMA number: 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed, 618 Bright Nickel, 619 Satin Nickel, 622 Flat Black, 624 Dark Bronze, 625 Bright Chrome, 626 Satin Chrome, plus 20 Antique Nickel. Match the BHMA number on your existing Schlage deadbolt rather than the finish name, since 626 satin chrome and 619 satin nickel read similarly in a catalog photo and do not match on the door.
8) Should I upgrade the cylinder or replace the whole deadbolt when a Schlage B Series lock needs better security?
If the deadbolt body is sound and the door prep is good, a cylinder swap is the cheaper route. The 20008S4 is a retrofit cylinder made to go into Schlage B, E and F160 Series deadbolts, so you get UL 437 drill and pick resistance and restricted keying without pulling the lock or touching the door. Replace the whole deadbolt instead when the bolt or housing is worn, when the prep is wrong, or when you want a different function. Across a portfolio, cylinder-only upgrades also let you standardize an entire building on one Medeco key system while leaving the existing lock bodies in place.
9) Can I key Medeco 20008S4 deadbolt cylinders into the same master key system as our other Medeco locks?
Yes, as long as the pin count and technology line up. The 20008S4 is a 5-pin cylinder available in M3 or Biaxial, so it masters alongside other Medeco cylinders of the same 5-pin family and keyway technology. Because Medeco builds the same key system across more than 100 cylinder and tailpiece designs, you can carry one key system from knob and lever cylinders through to these Schlage deadbolt retrofits. Order the sub-assembled version if your locksmith is pinning the system in house.
10) Is the Medeco 20008S4 rated for commercial use or is it a residential cylinder?
Commercial. The 20008S4 is a commercial-duty cylinder, machined brass construction, certified ANSI A156.5 Grade 1 for consistent performance in heavy-use applications. Grade 1 is the top ANSI durability tier and the level typically specified for office buildings, schools, healthcare, and multi-tenant residential entries where a deadbolt sees daily traffic.
