How to Disable Anti-Theft in Vehiclesby Contributing Writer; Updated June 12, 2017
The Vehicles comes standard with an Anti-Theft system, which sounds an alarm when the doors are opened or if someone attempts to start the Vehicles without the proper key. This system uses a "MyKey" program which means the key is programmed to the specific Vehicles. Without this key, the system will arm and will not start. Aftermarket anti-theft devices cannot be used with the system as it will cause starting problems on the Vehicles.

Open the hood of your Eclipse. Work with your car turned off.
Disconnect the negative cable of your battery by using an adjustable wrench to loosen the bolt and then pulling the cable out of its mount. Disconnect the positive cable in the same manner, and remove the cable from its mount. Always remove the negative cable first, or you may short-circuit the electrical wiring in your Eclipse.
Insert the tip of a slotted screwdriver into the gap surrounding the ignition switch plate located on the steering column. (The ignition switch is the piece of equipment in which you insert your car key.) Tap the butt of the screwdriver with your palm to loosen the panel. Remove the panel, and set it aside.
Locate the anti-theft alarm wire. Each trim of Eclipse has different wiring and may use different colored wires. Consult your owner's manual for a wiring diagram for your specific trim of Eclipse. If you do not have an owner's manual, call a local Mitsubishi dealer and ask a certified mechanic which color wire in your Eclipse is the anti-theft alarm wire.
Cut the wire using wire cutters, and wrap the exposed ends in electrical tape.
Replace the ignition switch plate, and tap it into place using your hands.
Locate the fuse box on the underside of your steering column. Reach underneath the steering column and pull the fuse box downward to expose the fuses.
Remove the anti-theft fuse using a fuse puller. The anti-theft fuse is labeled --- do not remove any other fuses.
Replace the fuse box.
Connect the positive cable of your battery by inserting it back into its mount and tightening the bolt with an adjustable wrench. Connect the negative cable in the same manner. Always connect the positive cable first, or you may short-circuit the electrical wiring in your Eclipse. Close the hood of your car.
Items you will need
Press the unlock button on your vehicle's key fob to deactivate the alarm. If you've misplaced your remote for the car, use the PATS programmed key to unlock the driver's side door. Then, put the key in the ignition and turn the key to the "on" position. The vehicle's battery should be on, but the engine shouldn't be running.
Locate the override button on the alarm box, beneath the driver's side of the dashboard. Press the button and hold it in until the alarm beeps one time. The LED light for the alarm should stop blinking, indicating the anti-theft system is disabled.
To reset the vehicle's alarm, put the PATS programmed key in the ignition and turn the key to the "on" position. Press the override button. When the alarm resets, it chirps two times and the LED light begins blinking.
Items you will need
PATS programmed ignition key
Turn the ignition key counter clockwise in the driver's side door to unlock the car. This deactivates the alarm long enough for you to gain access to the vehicle. Then, place the key in the ignition and turn the key until it clicks once. This starts the car's battery, but doesn't ignite the engine. The LED light on the dashboard should stop blinking, indicating the alarm is temporarily disabled.
Locate the box for the alarm under the dashboard on the driver's side of the car. Then, look for the override button on the box. Typically, the small button is either red or black. With the ignition key in the "on" position, press the override button and hold it in until the alarm chirps once. This disables the alarm until you manually reactivate it.
To reactivate the alarm, turn the key to the "on" position and press the override button once. The alarm chirps twice, indicating the alarm is active.
Items you will need
Unlock any door with the key.
Press the "Unlock" button on the key fob within 20 seconds.
Start the ignition within 20 seconds while the chimes are sounding. The anti-theft deterrent is now disabled.
