COBRA INSTALLATION AND PROGRAMMING GUIDE

Introduction / Tools and Materials Needed

Introduction

The MPC Cobra is a battery-powered manually programmed access control sys-

tem. Up to 100 individual codes can be programmed right at the keypad. A red and 

green LED on the keypad provide visual indication for programming and access 

events. Mechanical key override is possible when a 7-pin small-format inter-

changeable core (not included) is installed in place of the cylinder plug, which 

comes standard. Either the plug or the IC core must be installed for the lock to 

operate. When the cylinder is removed (using the cylinder control key) the lock 

will unlock. Manual key override should only be necessary if the low battery out-

put indications have been ignored. (See also 

BATTERY INFORMATION:

 on page 10

). 

The design allows for mounting on doors from 1-1/2” to 2” thick. A shim is avail-

able to mount the lock to a 1-3/8” door. An exterior gasket (EG option) is available 

for application to exterior sides of doors.

Installing the 6 or 7-Pin IC Core for Manual Key Override

1)   Install the 7-Pin Small-Format IC Core for Manual Key Override:

•     

Hold lock in horizontal position.

•     

Remove tape (

a

) if present.

•     

Push in plug (

b

) until pin (

c

) until it falls out.

•     

Remove plug.

•     

Insert cylinder control key (

a

) into core (

b

) and turn

clockwise to retract locking pin.

•     

Push cylinder core into lock

NOTE: Resistance will be noticeable.

•     

Turn key counterclockwise to engage locking pin.

•     

Remove key.

Lock is now operational.

Operation:

Either the cylinder plug or the IC core must be installed for the lock to operate. Removal of the core or 

plug automatically unlocks the lock. It is recommended that an IC core be installed in case it ever 

becomes necessary to unlock the lock using mechanical means.

NOTE: 

6-PIN IC CORE CYLINDERS REQUIRE THAT THE 
ADAPTER IS INSTALLED TO MAKE THEM AS LONG 
AS A 7-PIN CYLINDER. THE ADAPTER IS

Programming Lock Codes

57010-H                                              Page 10                                              12-19-2005

 

Programming Lock Codes

CODE FUNCTIONS:

The MPC Cobra is manually programmable to have up to 100 codes. The codes can have different functions as described below. Several 
types of functions have factory default values which are operational as soon as the lock is installed. It is highly recommended that the Pro-
gramming Code be changed (this will delete all factory default codes) and new codes be added. In addition, it is recommended that at least 
one Freeze/Lockout Code be added - in case the batteries get completely drained. (See “Battery Information” on below.) All codes can be 3-
8 digits in length (except the Programming code which must be 5-8 digits.) Keep a log of all issued codes. Issue codes exclusively with all 
odd or all even numbers - this practice will make it easier to spot duplicate codes, since each keypad button represents two numbers (for 
example, code 246 is identical to code 135.)

The programming code puts the lock into a programming mode. It will not unlock the lock. 
When a Programming code plus “*” is entered the LEDs alternately flash several times 
indicating the lock is in a programming mode. If more than 30 seconds pass in between 
programming entries, the lock returns to a normal operational state.

XXX

Normal codes

 unlock the lock for the relock time delay. While the lock is unlocked the 

green LED will flash. The LED will stop flashing and the lock will relock.

xxx

Toggle codes

 unlock the lock indefinitely. When the same (or another) toggle code is 

entered, the lock will immediately relock. When a toggle code is entered, the green LED 
will flash once. The LED will stop flashing and the lock will relock.

xxx

Freeze/Lockout codes

 prevent other codes from working. The lock can be locked or 

unlocked when one is entered. If it is locked, a Pass Thru code will unlock it but all other 
codes will not. Only another Lockout code will reverse the effect.

xxx

One Use codes

 unlock the lock for the relock time delay. They will only work once and 

then are deleted from memory. They can used again if they are programmed (added) into 
memory again.

Supervised codes

 require that two different supervised codes entered in order to unlock 

the lock for the relock time delay.

xxx

Pass Thru codes

 will  unlock the door for the relock time delay even if the door is in the 

lockout mode.

CLEARING MEMORY:

Clearing memory will delete all programmed codes and restore factory default 
codes. If the memory ever needs to be erased follow the steps below:

1. Remove the inside escutcheon. Remove one of the batteries.
2. Press any key.
3. Hold down the “*” key and reinstall the battery. Continue holding the “*” key 
down. The red LED will flash a few times and then stay on.
4. Release the “*” key. 
5. Install the inside escutcheon.

Note: to return the lock to the factory default relock time delay, do steps 1-4 twice 
in a row.

BATTERY INFORMATION:

The MPC Cobra uses four, standard AA batteries. 
The batteries should provide enough life for 
approximately 80,000 lock/unlock cycles. When 
the batteries are running out the lock provides two 
different modes of low battery indication: First, 
when a code is entered, the red LED will flash 
twelve times before the lock executes the com-
mand of the code. This is an indication that it is 
time to replace the batteries. The lock will go for 
about 500 cycles in this condition. After it reaches 
a certain point the lock will go into “Low Battery 
Lockout” mode. A Freeze/Lockout code will need 
to be entered in order gain access. If the batteries 
are not changed, the lock will eventually not work 
and manual key override (if installed) will need to 
be used.

Programming Steps

Use the steps on this page to pro-
gram codes into the lock. The “*” key 
is used like the <ENTER> key is on 
a computer. After pressing the “*” 
key, wait for the red and green LEDs 
to stop flashing before proceeding to 
the next step. If at any time the red 
LED stays on while the green LED 
flashes an error has occurred. The 
flashing message will repeat three 
times. Count the number of flashes 
and consult the error code chart 
below.
