Purely for curiousity, can we substitute Schlage key pins for Kwikset key pins, or vice versa? We can! Just not in production, please.
The measurements for Kwikset-pins-in-Schlage-systems were made by me using a decent SC1 key (specs) and Kwikset pins (specs) in good condition, but your mileage may vary.
| Kwikset | Schlage | ||
|---|---|---|---|
| Cut depth | Measurement (in) | Measurement (in) | Cut depth |
| 0.165 | 0 | ||
| 1 | 0.172 | ||
| 0.180 | 1 | ||
| 2 | 0.195 + 0.013 = 0.208 | 0.195 | 2 |
| 0.210 | 3 | ||
| 3 | 0.218 | ||
| 0.225 | 4 | ||
| 0.240 | 5 | ||
| 4 | 0.241 + 0.013 = 0.254 | ||
| 0.255 | 6 | ||
| 5 | 0.264 | ||
| 0.270 | 7 | ||
| 0.285 | 8 | ||
| 6 | 0.287 + 0.013 = 0.300 | ||
| 0.300 | 9 | ||
Add ~0.013 to Kwikset pin measurement, due to reduced bevel of Kwikset pins.
(KW ~2, 4, 6 to SC 3, 6, 9)
No measurement adjustment.
