The price is forbidding our small income expenses. . .BUT if you can determine my explanation below that your bypass is compatible with ours? We, I, my wife and baby, are confined in the seculed place in Hayfork mountains. . .I am seeking for main stand-alone switcher that turns off against fuel pump, against inner dome light, against rear trunk lid light, against auto transmission and against four door lock actuators . . .I successfully made it run with bypass starter relay and hot wired down to gas tank pump and it runs well but "service immediately" light stays on.. and auto transmission starts on 3 rd gear that stalls engine, it wont start on second gear. . .when arrived home on uphill road it wont go up so I drove it on reverse and finally parked here. . . I KNOW it is a few steps ahead where stand-alone switcher are. I am going to follow the dome light's wire down to the place where relay-switchers are. . or follow gas pump wire that I assume can be very hard way to do. . but before I go ahead that if you can tell me where those switchers for A/T, fuel pump,inner lights, doors are located?? in 1998 SL1 ? that would really save my searching . . . Your tips without having to purchase your bypassing kit would be greatly appreciated. Sincerely, Donald

The most common cause is the chip in the key does not match the security code, or the security module has failed. The chip in the key must match the factory setting to allow the car to start.
If it worked before you replaced the lock cylinder, you need to have a new key with the same old chip cut to the new lock.
If code 53 involves the PASS system for your car, the chip in the key has failed, or the sensor in the lock cylinder, or the control module. The anti-theft system disables the starter and the fuel injectors. You could bypass those circuits to get the car started.
The problem is in the key or ignition. Aside from the key working like a normal key, it also has a chip or transponder in it that is part of the security antitheft system. The key is then read by the ignition and must communicate the correct signal. If there are any break in communication, the system goes into anti theft and locks out the starter. Might be a key issue or an ignition issue. The fact that the light is flashing, indicates key or ignition. If it were solid, then the problem would be the Theft Deterrent Module (TDM) that is the main computer of the security system. You can either fix the problem part, take it to a dealer who is authorized to fix it, or bypass it entirely. This link explains the system and how you can fix it yourself.
Yes there is a bypass. Costs about $200.00. You should be able to put the key close enough to the cylinder to get the security to go off. I don't know what you did to get the cylinder out. but there is a chip mounted to the steering column. once the key is close enough to it it will let the car start. If you broke the chip getting the cylinder out then you have some money to put out to get it running.
Sometimes the original anti theft system put in by GM can cause a no start situation. The key needs to communicate with the ignition and then the ignition communicates with the TDM computer. (Theft Deterrent Module) The TDM then allows the car to start. When installing remote starts they tend to "bypass" the key ignition part of the security system. This will then eventually ruin the TDM. If you see a light on the dash that says SECURITY, then this is 100% your problem.

You have to do a relearn procedure on the anti-theft system:
Attempt to start the vehicle. Leave the ignition on until the THEFT SYSTEM indicator turns off (about 10 minutes). Turn the ignition switch off. Leave the ignition switch off with key in for about 10 minutes. Attempt to start vehicle.
YOU CAN CRANK VECHICLE BY PUTTING KEY IN THE IGNITION SWITCH IN ON POSITION FOR 10 MINUTES UNTIL SECURITY LIGHT TURN ITSELF OFF.THEN TURN OFF IGNITION SWITCH FOR 5 SECONDS THEN START ENGINE.YOU CANT BYPASS THE THEFT SECURITY SYSTEM BECAUSE ITS A FEATURE THAT CAME WITH TRUCK.THEFT SECURITY SYSTEM IS CONTROL BY BCM AND PCM. IF YOUR IGNITION KEYS AND SWITCH IS FAULTY ALSO THE BCM THEY ALL HAVE TO BE REPLACED AT DEALERSHIP AND REPROGRAMMED CANT BYPASS SYSTEM YOU HAVE TO GET IT FIXED.
The anti-theft module on other GM cars is included in the engine computer. Try this: wipe down the resistor contacts on the key with rubbing alcohol until they are nice and shiny (the resistor is the black blob embedded in the shank of the key and
the contacts are the metal pieces in the middle of the resistor). Spray a shot of lubricating contact cleaner into the ignition lock, insert and remove the key several times, then wipe the key off again. Hopefully your problem is contamination causing the computer to read too high a value for the resistance and this will clean it up. (Note: a non-lubricating contact cleaner may cause problems for the mechanical part of the lock by stripping off its lubricant. Never use a graphite-based lock lubricant on an anti-theft ignition switch. The graphite can form a current leakage path around the key resistor and cause a low reading, which will be interpreted as a false key. If this case, you will either have to tear down the ignition lock and clean it by hand, or replace it.)
It is possible that the contacts in the ignition lock are broken or worn, or the wiring in the steering column is bad. If you need to bypass the anti-theft system, let me know and I'll tell you privately how to do it - I don't want to tip off car thieves to this trick!
