The Passlock family has two basic relearn procedures-a ten-minute procedure and a thirty-minute procedure-and which one you use depends on the system and what components have been replaced.
The ten-minute procedure involves trying to start the engine. If nothing happens or the engine starts and dies, the security light will be flashing. Wait ten minutes. The flashing light should go off or illuminate without flashing. When it does, turn the ignition off, wait twenty seconds, and then try to start the engine. If it starts and runs, everything is okay. If you get the same result as previously-nothing happens or the engine starts and dies with the security light flashing-wait ten more minutes.
You will now begin the thirty-minute relearn procedure, which is just the ten-minute procedure repeated three times. After turning the ignition off for the third time and waiting for twenty seconds, the engine should start and run. If it doesn't, there may still be something wrong with the system.
After the learn procedure is completed and the engine is running, the security light may stay on steady for a few minutes and then go off-this is normal. Depending on the system, replacement of key components will necessitate that a relearn procedure be completed. These include the ignition lock cylinder, Powertrain Control Module (PCM), Body Control Module (BCM), or Instrument Panel Cluster (IPC) ............ .Logic lock-up is an internal software issue within a control module which may be cleared by disconnecting and reconnecting the affected module (re-booting the system).
Electronic control modules can develop internal software issues which can cause erratic or no operation of the affected module. In most cases the module can be restored to proper operation by electrically disconnecting and reconnecting the affected module, just as you would reboot your home computer when it begins acting strangely.
Repeated Logic Lock-up failures of the same module would normally warrenty replacement of the affected module.
SOURCE: 1995 Buick LeSabre won't start when security light comes on.
When my 1994 LaSabre had a problem recognizing the chip in the key (due to the contacts in the lock not working), I managed to bypass the system by locating the two wires (clear tube with two smaller wires in it exiting the steerin column, unlike any other wiring), cutting the cable, and soldering a resistor across the two wires that go to the hidden module thet in turn controlls the starter and sends a signal to the engine computer. Use a resistor of the same resistamce value as in one of the keys for the car (measure resistors with a digital meter). There are a dozen or so values used. You loose the extra protection of the chip, but the fix is low cost.

Ok..
Your vehicle is equipaded with Factory Anti Theft System.
Called Pass key II . If the mechanic found the Code
Pass key error....
Is there a few test to Do. to know exactly the problem.
1--- check if the Old and New key Are equipaded with a Little thing (Chip or Ressistence) in the center of the key.
If not you need a key with the chip. and the correct Ohms.
2. If you just replace the battery,
Full charge the battery Attemp to start the vehicle and leave the key in run position for exactly 11 Minutes, Them turn the key to off position for 30 seconds and try to start, if the vehicle start . you did the prosses to program the key.
If the vehicle not start.
Some times this procedure will require Up to 3 times to setup.
Or more with intervals of 30 minutes,, But if not start.
Remove the lower cover of the steering column. and the the Connector orange with 2 white wires shielded with a orange cover.
NOTE.. Be sure to not Confuse with the Yellow wires and connector, They are for the AIR BAG. Dont use a Convencinal Test light on any of the Mentionated wires....
After you find the wire and saw everything ok.
3-- You will need to remove the Ignition Lock cylinder.
The ignition lock cylinder is use 2 white wires shielded with orange cover, On 90% of the cases one of the wires come broken. and the ECM loss the comunication with the Chip incrusted in the key..

I had the same problem with my 95 Lesabre. The owners manual says to take the key out, and wait 3 minutes(until the light goes off). It should fire right up.
SOURCE: pass key stays on1995 buick roadmaster car want crank
Short circuit probably not the problem. The pass key system is not being disabled making the car inoperable, thats why it will not crank. Either you are using a key that does not have the correct resistance(black chip in key) or if it is the same key you always used then the pass key sensor went bad. I believe it is in the steering column and a qualified mechanic could help you there.

30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help.
