Security pass-lock?

2003 doesn't use a resistor, it uses a pass-lock system. There is a sensor in the ignition cylinder that is activated when the lock cylinder rotates and a magnet on it tells the system you have a valid key. If they destroyed the lock, then those parts are gone and will need to be replaced and then the security system programmed before the engine will start again. That is because unlike the earlier system (passkey) that used resistors the pass-lock uses a signal from the hall effect in the lock to generate a specific signal for the components in it. The security system is then programmed to only respond to that signal. Makes it harder to steal that way. There are companies that make bypass boxes, but I have never seen one that reliably worked. Your best bet would be to tow or similar to get it to a place you can work on it. Then replace the damaged column. Just be sure you use a column from the same are so a 02-04 should work. Then have an automotive locksmith rekey the replacement column to match your keys, that way the other locks also match the keys, and you don't accidentally cause damage using the wrong one. You don't need to replace the BCM or PCM when replacing the column, you just need to do a relearn. However, to do that you need 2 valid keys, which is the reason why I say to have the replacement cylinder keyed to fit your original keys, you already have them so the relearn becomes easier.

The pass lock sensor is a part of the ignition lock cylinder housing where the key is inserted. The magnet is part of the ignition cylinder itself and is the piece that rotates inside the housing. They need to be a very precise distance apart to work. Another part of this is the anti-tamper section of the sensor. If the lock cylinder is removed the correct way, using the key to rotate it into position and then pushing the release there is no problem. You reverse that and it works. However, if it is removed by force like a hammer or slide hammer the anti-tamper part sends a signal to the PCM that someone is trying to steal the vehicle and it basically shuts it down, until it sees the new signal from the repaired system and then you can do the relearn. The mechanical ignition switch only selects the current path; it doesn't do anything for the security system side.
