Anti theft locked my car - security system problems?

Hi,

If you can't shift into gear from park, there is an issue with the park interlock system. Don't laugh, but do the brake lights work properly? The release actuator receives power from the brake light switch to release. Battery voltage is supplied at all times through "fuse 47" to the brake switch. With the ignition in "on" (II) or "start" (III), battery voltage is supplied through "fuse 9" (in the driver's under-dash fuse/relay box) to the shift lock solenoid.

This is where I would start. I need you to check both of the fuses I indicated. I attached a few pics to help with identification. Let me know if they help. Also, here is a link you may find helpful:

Let me know what you find or if you have other questions.

Take care,

You need to replace the lock actuator on the driver side. Take out the screws in the door pull and the inside door handle. The bottom of the door should be unsnapped with a slight pressure from a screwdriver slide along the bottom. This guide can help us fix it.

Hi bananuh,

Something is not providing the correct contact and it is not easy to isolate the cause.

I would suggest checking the beltings and alternator charging rate. Check for loose or contaminated connectors and bad grounding straps.

Hi sayre2242,

When the doors locks are sluggish, it is usually because the actuators are weak or the power supply connections are poor or the battery is weak.

It has nothing to do wit the remote batteries. You need to check the door lock actuators linkages for proper lubrication.

With regard to the one door that does not respond, that one actually had the actuator go out. Sounds like the rest are getting weak.

With regard to the battery in the remote, many of us by the battery from say Walmart. I have had experience with weak batteries from them. But like KHLow stated the weak battery is not the issue.

One of the most common cause of such problems are due to door switches. It could be a faulty door switch or its cover, doors out of adjustment or the hood switch.

Sit inside vehicle and close all doors with room light set to turn on when doors are opened. You may leave the windows open. Gently push at lower rear portion of each door inner panel and note if the room light comes on. For any that turns the room light on, you need to check the door switch and door adjustment.

The hood switch should be checked as well.

Hi sissygirl,

When it does not start, were the dashlights showing?
Were you able to crank the engine?
Was the security key light blinking?

When problem occurs and starting is not possible, you need to check if it is ignition, ie. sparks or fuel that is not available.

Here is a link from which you can understand how to check for missing sparks or fuel.

Let me know what you find. From your description, it is possible the fuel pump or its circuit is intermittently malfunctioning. It coud be a faulty ignition switch as well.

Hi chuck4271,

The triggering points are the door and hood switches. Check if any of them are not functioning well or if any doors are out of alignment which would trigger the alarm if there are any movements due to external forces. Eg wind, vibration when heavy vehicles moves by.

If equipped with vibration/impact sensors, you need to recalibrate it.

Hi Kirby18,

Thank you for the donation.

The factory alarm cannot be disabled as it is linked to many other components such as the central locking etc.

For the alarm to go off randomly, the cause are usually the door or hood switches. Check if any of the doors are out of adjustment or door switches rubber cover are missing.

If any of the door ajar indicator is intermittently blinking, that is the door that the problem is coming from. If they do not occur, the most likely source would be the hood switch.

Hi andrew rivera,

For safety reasons, the clutch is required to be depressed while starting manual transmissions.

If you wish to install an auto start, you need to ensure that the transmission is always in neutral when the system is operated.

An additional relay to bypass the clutch switch would be required.
