Rekeying CES  Euro / Profile  Cylinders

Rekeying CES to a Schlage key is not simple. The Schlage pins are about 15 thousands to long and the spacing on the key is slightly off on the first  cut, closest to the bow of the key blank.  It appears, using 5 thousands pin kit, the standard pin number  is one number  high. If a Schlage calls for a # 6 pin = .255, it will use the next one done or a  .240 bottom pin.  I have not tried master keying at this time. Also because the  spacing is slightly off on the first  pin you will need to reduce that pin by 5 thousands. The first pin does not hit the bottom of the valley and rides

The Schalge key blank is about 1/32” shorter than the CES. The  duplicate keys cut on Schlage SC-1 blanks work OK, I did notice that the key needs to be pushed all the way in or sometimes the tail piece / cam would not engage.

            The second option is to purchase a CES keying kit. # 2036576. The small kit has enough pins, drivers and springs to rekey 10 locks and comes with a key gauge.

Steps to rekey CES cylinder.

1. Remove plastic cap; the cap has small barbs on both sides that lock into cylinder housing. The cap can be re-used if removed without damage. I found the best way to remove is squeeze the sides in and use a thin shim on both sides, lift cap.
2. Remove springs – These are longer than normal
3. Remove all driver and bottom pins.  Save driver / top pins
4. Decode Schlage key  and load new pins into cylinder holes – remember the first slot is smaller.
5. Re-load the driver pins, then springs.
6. Hold springs down with finger and try key.
7. Snap plastic cap on after removing key; take care  not to bend springs.

Note: I have not tried rekeying to CES key, I assume the pins are the same.

 If having trouble keying, I would suggest pinning one cylinder at a time and continue to the next when it works.
