The KnoxLock® SFIC*Retrofit eLock core is designed to replace a mechanical Small Format
Interchangeable Core (SFIC) and is compatible with most locking hardware having a SFIC prep. Many lock
types are available in SFIC format.
IMPORTANT: KnoxLock SFIC is not compatible with large format interchangeable core (LFIC) cylinders and
preps. It may be dicult to distinguish between SFIC and LFIC when looking at installed mechanical cores.
Please consult with your facilities personnel or a locksmith for assistance in determining the compatibility of
your installation.
NOTE: Indoor lock cores can be converted for outdoor use by replacing the faceplate cover with a rain
guard. Faceplate covers and rain guards are field replaceable. For lever handles having a teardrop cylinder
opening, a curved spacer can be ordered separately to replace the standard spacer.

PREREQUISITES:
• Remove the existing SFIC mechanical lock core (if any) according to the manufacturer’s instructions
using the control key that was provided with your mechanical SFIC lock cores
• Configure and sync the KLS-8720K SFIC Control Key in KnoxConnect to enable Command Code 1 and
Command Code 2
• In KnoxConnect, verify the eLock serial number or register the KnoxLock SFIC core to your jurisdiction
if not found
• Program the KnoxLock SFIC with the desired lock code before attempting to install the lock:
• To program the eLock enter Command Code 2 on the Knox SFIC Control Key and insert into lock
• Hold without turning until the eKey LEDs flash green and cease
• Test the lock open function using a standard eKey enabled with Command Code 1
CAUTION:
Open the enclosure/door/shackle being secured by the lock you are replacing. Do not allow the door
to close until installation is complete and the unlock function has been tested. You may be unable
to reopen the door if these steps are not completed.
Do not use the Control Key to perform normal unlocking. The Control Key is not retained in the
eLock core. It is possible to remove the eKey before the unlocking sequence is complete, leaving the
lock in a disabled condition and requiring potentially destructive measures to remove the lock core.
TOOLS REQUIRED FOR INSTALLATION:
• User key and control key for existing
lock cylinder
• Knox KLS-8720K SFIC Control Key
• Knox KLS-8701K Standard eKey
• T-10 Tamper-Resistant Torx screwdriver
• Hex screwdriver 0.050”

KNOXLOCK® SFIC
INSTALLATION GUIDE
LOCK INSTALLATION
1. Activate the Control Key and insert it into the lock
core. Once the Control Key shows solid green
LEDs rotate the lock core plug ~45°. Remove the
Control Key and check the alignment to ensure
the core is clear of the screw guard.
2. Use the magnet on the backside of the Control Key
to remove the screw guard.
3. Use a T10 tamper resistant Torx screwdriver to turn
the eLock’s installation screw counterclockwise
until the control lug is fully retracted and the screw
stops. Do not over tighten.
4. Place the spacer ring onto the eLock core so that
the spacer and core create a flat surface when
installed into the cylinder.
5. Insert the eLock into the SFIC lockset’s cylinder
receptacle. Use the Control Key to align lock
core pin holes with the position of the lockset’s
throw member pins if necessary and use the Torx
screwdriver to turn the installation screw clockwise
until the screw is tight. Gently pull on the lock to
confirm the eLock is firmly installed.
6. Test the lock using a standard ekey to verify
unlocking and locking performs as intended.
7. Activate and use the Control Key to rotate the
lock core plug ~45° so that the notch on the lock
core plug is aligned with the Screw Guard tail. If
necessary, use the Control Key to readjust.
NOTE: In some applications (e.g. latch locks) it
may be necessary to hold the latch down so that
that the lock core plug is not rotated back by the
latch spring.
8. Insert Screw Guard.
9. Use the Control Key to rotate the Lock Core Plug
back into the locked position.
10. Install the faceplate cover or rain guard. Place the cover or
rain guard onto the face of the eLock, aligning the holes
with the screw holes in the lock. Using a 0.050”- size hex
screwdriver, insert the screws through the faceplate cover
or rain guard and tighten.
Your installation is now complete.
TO UNINSTALL THE LOCK
1. Remove the faceplate cover or rain guard using a
0.050” – Hex screwdriver.
2. Use the SFIC Control Key with Command Code 1 to
rotate the lock core ~45 degrees so that the notch on
the lock core plug is aligned with the Screw Guard
tail.
3. Remove the eKey from the SFIC eLock and use the
magnet on the butt of the Control Key to remove the
Screw Guard.
4. Use a T10 Security Torx screwdriver to unscrew the
installation screw until the screw stops.
5. Remove the KnoxLock SFIC from the lock receptacle.
