The anti-theft device of your car (officially known as the PASSLOCK II key
based engine disabling system) is triggered and it's doing what it's supposed to do - it prevents the car from moving by cutting the power to the engine's ECM and blocking the lever of the transmission. If you can't disable it then it's faulty.
The only thing you can do is to reset it: put the key in the ignition, turn it on to just before cranking and then leaving it that way for 10 mins. If this doesn't fix it then you will have to have the car towed top a dealer. They will inspect the system and fix it: if you're lucky all it will needs is a full reprogramming - this will cost you around $200; if you're unlucky the module itself is faulty and it will have to be replaced and reprogrammed, at a cost of around $1000.

SOURCE: The anti theft isn't recognizing my key, and will

This comes from personal experience on my Mother's '03 Impala. Apparently the chip in the key died. Tried the spare key that came with the car and it all works again. If this solves your problem (as it did mine) just go to your dealership and have a new key cut.

Where is location the automatic transmission shift lock relay in my s10 1998 2.2 2wd

Automatic Transmission Shift Lock Control Description
The brake transmission shift interlock (BTSI) system prevents the automatic transmission from being shifted out of PARK unless the brake pedal is depressed. When the brake pedal is depressed, the BTSI solenoid releases a lock pawl. This enables the shift linkage to move and the shift lever to operate.
When service operations are required, the BTSI system can be overridden.
On vehicles equipped with a column-mounted shift lever, override the BTSI system by performing the following steps:
  1. Turn the ignition switch to the OFF position.
  2. Remove battery voltage from the solenoid.
  3. Turn the ignition switch to the ON position.
For vehicles equipped with floor-mounted shift levers, an override lever is mounted on the right side of the assembly. The override lever can be accessed by removing the shift lever boot. Push the lever to the left in order to override the BTSI.
Which does your S-10 have column or floor shift ? No relay ,has a solenoid .
With Column Shift A/T
The brake transmission shift interlock (BTSI) system prevents the automatic transmission from being shifted out of the PARK position unless the following conditions are present:
The brake pedal is depressed.

The ignition switch is turned to the RUN or the START position.

When the ignition switch is in the RUN or the START position, the current flows from the B/U Lamp fuse located in the underhood bussed electrical center (UBEC) through CKT 839 (PNK) to the park/neutral position switch. The park/neutral position switch also feeds the backup lamps portion of the switch. With the transmission in the PARK position, the current flows to the BTSI fuse located in the underhood bussed electrical center (UBEC) through CKT 275 (LT GRN). The current then flows to the TCC/stoplamp switch through CKT 584 (LT GRN/BLK). The current continues to the BTSI solenoid through CKT 1135 (DK GRN/WHT). The ground path is provided through CKT 1850 (BLK) to G207. When the brake pedal is depressed, the normally closed contacts in the TCC/stoplamp switch open and the current flow is interrupted. When the current flow is interrupted, the BTSI solenoid de-energizes. The transmission may then shift to another gear. When the transmission shifts to another gear (except PARK), the contacts in the park/neutral position switch open. This condition stops the current flow to energize the solenoid when the brake pedal releases.

1998 sunfire in codep1629, how do I fix it

You may want to do some research on the code. The basic problem is the anti-theft system is not seeing a crank signal and shutting down the fuel pump. It could be the security system, or the crank sensor, or other issues.
If you have auto start or a remote starting system it can cause these problems too.

2004 cts bake lights will not come on just setting car has to be on is that a bad bake switch and car is stuck in park

most modern cars (and trucks, too!) have a safety system that prevents someone from shifting out of park if the brakes are not pressed (it helps keep small children from moving the car out of park), check the switch(es) on the brake pedal to see if A) it (they) are getting power, and B) that the power is going thru to the brake lights/ brake interrupt solenoid.

After starting engine shifting lever will not come out of "park".

You probably have a blown fuse to teh shift lock solenoid or the brake lights. See if you have brake lights first. If no, check the brake swithc on the brake pedal arm.

There is an emergency bypass procedure in owner manual.

Car won't go in drive without using override button

does your brake lights work? it's sounds like the shift lock solenoid isn't working it could be not getting a signal from the brake light switch or if it is getting signal then the shiftlock solenoid is bad but make sure the solenoid is getting a signal from the brakelight switch first

I think your brake shift interlock solenoid is not releasing the Park position when you apply the brake.

Check for a blown fuse first. see owner manual for location of fuse.

Also, check owner manual for how to manually bypass the interlock.

When you step on the brake pedal, it activates a solenoid that unlocks the shift linkage cable so it will move. It is a safety feature to ensure you have you foot on the brake and not the gas, as you shift out of park.

please rate highly if this helps.
