Kwikset 85174-SLVR – Frequently Asked Questions
1) Will the Kwikset 85174 cylinder fit my 980 deadbolt?
Yes. The 85174 SmartKey cylinder is a direct replacement for Kwikset single cylinder deadbolts including the 553, 800, 980, 780, 158, 687 and 660. It also drops into Kwikset electronic deadbolts: 620, 888, 907, 909, 913, 915, 916, 919, 925, 938, 939, 942 and 953. If your deadbolt is not one of those Kwikset models, this is not the cylinder for it.
2) Can I key this Kwikset SmartKey cylinder to my existing Schlage keys?
That is exactly what this one is for. The 85174 takes the Schlage C (SC1) keyway, so it accepts an SC1 key blank rather than Kwikset's own KW1. If a property already runs Schlage-keyed hardware, you can bring a Kwikset deadbolt onto the same key instead of carrying two blanks. Note it is the keyway only that matches; the cylinder still installs in a Kwikset deadbolt body.
3) Do I need a locksmith to re-key a Kwikset 85174 SmartKey cylinder?
No. SmartKey Security re-keys in place, without pulling the cylinder apart, using the SmartKey tool and a working SC1 key plus the new key. For a property manager turning units, that means a tenant change is a bench-free job at the door, and the same cylinder can be re-keyed again on the next turn.
4) What do I choose between keyed alike and keyed different when ordering a Kwikset 85174?
Keying is a required selection on the 85174 and it is free either way. Pick keyed alike when you want every cylinder in the order to open on one SC1 key, which is the usual choice for a building or a unit where one key should run all the deadbolts. Pick keyed different when each door needs its own key. There is also an optional key code field, so if you are matching an existing SC1 key section already in service, enter that code and the cylinders arrive on that key.
5) Can I use the Kwikset 85174 to fix an electronic deadbolt whose key override stopped working?
Yes, on the Kwikset electronic models it covers: 620, 888, 907, 909, 913, 915, 916, 919, 925, 938, 939, 942 and 953. It is a mechanical cylinder, so it replaces only the key override side; it does not touch the keypad, motor or electronics. If the fault is in the electronic side, swapping this cylinder will not resolve it.
6) Do I replace the whole deadbolt or just the cylinder when a key is lost or a tenant moves out?
If the deadbolt is a Kwikset model on the compatible list and the hardware is sound, the cylinder alone settles it. With SmartKey you can usually just re-key the existing cylinder in place with no parts at all. You buy the 85174 when the cylinder itself is worn, damaged, or when you want to convert a Kwikset deadbolt over to the SC1 keyway so it runs on the same key as Schlage hardware elsewhere on the property.
7) Does the Kwikset 85174 come in a finish to match my existing deadbolt?
Two finishes are offered on the 85174 cylinder, Black and Silver. On most Kwikset deadbolts only the keyed face of the cylinder shows through the exterior escutcheon, so match it to the trim you already have on the door rather than to the whole lock body.
