Emtek CY4 Cylinder (Each)

The CY4 is cut to Schlage C keyway as standard, which is the most common residential keyway in North America. If your other doors are already on Schlage C, a locksmith can key the CY4 to match that existing key so one key runs the whole house. Out of the box it ships with 2 keys of its own, so plan on either rekeying it to your system or living with a second key.

Two things: function and finish. The CY4 order form requires you to state both, so have the lock function you need (which side keys, single or double cylinder application) and the finish that matches the rest of the Emtek trim on the door before you order. It is sold each, not in pairs, so a double cylinder opening needs two.

The Emtek CY4 is a residential door hardware cylinder. A mortise lock body needs a mortise cylinder: the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder that also uses the Schlage C keyway, so an existing Schlage C key system carries across. The Corbin Russwin 1000 is a Grade 1 series mortise cylinder, 1-1/2 inch, with an A02 straight cam, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder with a 1/2 inch minimum door thickness. Cam style and cylinder length have to match the lock body.

The Emtek CY4 is a brass cylinder supplied on the Schlage C keyway with two keys. Where a high security key system is wanted on the same Emtek handleset or deadbolt, the Medeco 1065140 is a 5-pin retrofit cylinder built for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder position, and the Medeco 1065244 is a 5-pin rim type lazy motion cylinder supplied with an Emtek tailpiece. Both change the key system away from Schlage C, so every door keyed alike with the CY4 has to move with them.

The Emtek CY4 is an Emtek replacement cylinder supplied on the Schlage C keyway. For a Kwikset single cylinder deadbolt, the Medeco 1012040 is a 6-pin lazy motion rim cylinder made for that application. Matching the cylinder to the lock body it drives matters more than matching the keyway, because a cylinder that will not engage the deadbolt tailpiece cannot be made to work by keying.

The Emtek CY4 comes on the Schlage C keyway as standard, so a substitute that holds the key system has to carry the same keyway in a different body. The Detex MC65 is a 6-pin mortise cylinder on the Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, finished 643E aged bronze. Both let existing C keys stay in service while the cylinder format changes to suit the lock.

No, the CY4 is a straight mechanical brass cylinder keyed to Schlage C. There is no electronics in it, so it will not work as a replacement part inside a keypad or motorized Emtek lock. It is the key cylinder for mechanical Emtek trim.

No. The CY4 is a fixed brass cylinder in Schlage C, not an IC housing, so it cannot take a core. For an interchangeable core program, look at the BEST 1C Series standard 5-pin core, the BEST 1CB 150 Series interchangeable core, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Those let maintenance swap a core instead of pulling the cylinder.

Two. The CY4 is sold as a single cylinder, each. A double cylinder deadbolt keys from both sides, so it takes one on the exterior and one on the interior. If you want them to work on the same key, order both and have them keyed alike, since both come standard in Schlage C.

It does not. Rim cylinders drive a tailpiece through the device and are ordered by cam orientation: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, the 20-022 is the same cylinder with a horizontal tailpiece cam, and the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The Emtek CY4 is a residential cylinder for Emtek door hardware.

The Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, so it is the generic form of the same driving arrangement rather than a brand specific tailpiece. The Medeco 1065244 is the version that arrives with an Emtek tailpiece. The Emtek CY4 is a brass cylinder on the Schlage C keyway; confirm the cam or tailpiece the opening needs before choosing between the two Medeco parts, since that is what separates them.

No. The Emtek CY4 is a brass cylinder that drops into an Emtek lock. The Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws designed for use with the Adams Rite MS1847 deadlock or deadlatch, the 4024 is the same pull with a trim plate mounting for the MS1847, and the 4026 is the wood door version for the Adams Rite 5017 deadlock or deadlatch. Those parts combine the cylinder with a pull for the buyer to grip, and they are tied to specific Adams Rite lock bodies rather than to an Emtek set.

Not directly, because the CY4 is a fixed brass cylinder rather than a core housing. Facilities that want core swap rekeying move to an interchangeable core system: the BEST 1C is a standard 5-pin cylinder core, the BEST 1CB is a 150 series interchangeable core cylinder in the Peaks line, and the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass. The Corbin Russwin 1080 is a 1-1/2 inch 6-pin large format interchangeable core mortise cylinder with an A01 cam for Schlage L9000 mortise locks. Each requires the lock to accept that core format.

The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, the 1549 is a key-in-deadbolt cylinder, and the 1579 is a knob and lever cylinder for Sargent locks. The Falcon A23161-05 G is a key in lever cylinder from the RU/T series, 6-pin G keyway, keyed different, supplied with two cut keys. The Emtek CY4 covers the Emtek side of that same job on the Schlage C keyway with two keys, so the choice comes down to which lock body the cylinder has to seat in.

Not with a single part, but the key system can be held constant. The Emtek CY4 is a residential cylinder on the Schlage C keyway; the Detex MC65 is a 6-pin commercial grade mortise cylinder on the same Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core in the C keyway. Standardizing on the C keyway lets one key hierarchy cover both door types while each opening still gets the cylinder body its lock requires.

Solid brass. Brass is the standard material for exterior residential cylinders because it resists corrosion in weather, and it is soft enough to be rekeyed cleanly by a locksmith. This is Emtek's residential cylinder, so it is sized for house and light multi-family openings rather than high traffic commercial entries.

No. The BEST 12E series dummy rim cylinder is 1-5/32 inch in diameter and, being a dummy, carries no working key mechanism, so it fills a cylinder opening for appearance rather than locking the door. The Emtek CY4 is a keyed brass cylinder supplied on the Schlage C keyway with two keys. A dummy only suits a hole that needs covering on an inactive leaf or a decorative position.
