Not sure about the parking lights. But the warning chime is controlled by a sensor in the key lock.

No one can explain the complexities of wheel alignment on this site and in any event you do not have the correct equipment to undertake an alignment on the vehicle. You will have to take it to a tire dealer or suspension specialist to have the wheel alignment carried out.

SOURCE: reverse lights stay on even with the keys out of the ignition

your transmission switch needs adjustment or broken if you can turn the vehicle on in park setting.

SOURCE: Door Ajar light and dinger, interior lights stay on, looking for a fuse diagram.

It drove me nuts too. Fortunately, the solution is both cheap and simple. There is a latch mechanism in each side of the tailgate which gets all filled with dirt and slime.The latch jaws start to stick and dont move far enough to close the door ajar switch inside the tailgate Spray each latch generously with WD40, wipe the mechanisms off with a rag, close the tailgate, open the tailgate and repeat the cleaning several times. As soon as you get everything freed up, the switch will be able to report that the tailgate is closed and the problems will be gone. If you want, afterwards you can spray a little lithium grease on the latches to keep things running smooth. You may need to use a screwdriver to completely pry open the jaws in conjunction with opening the tailgate handle to get them to open fully while you are washing and wiping them off. Now's a real good time to lubricate all the door hinges and latches including the sliding door. May as well put some oil on the hood hinges and hood latch too.It's not impossible to keep Fords on the road....just tricky......very tricky.

Turning the ignition of my jaguar x type 2003 does not turn engine over but the security light indicator flashes. Is there a way to reset?

If the security light is flashing that means the car does not see the chip in the key.
Either the chip in the key is missing or broken.
The antenna ring around the ignition lock has gone bad or been broken.

You can take the key to a locksmith and they can tell you if the chip in the keys is there and operating OK.

can be a problem between the transponder chip ignition key and the engine imobilizer
may be a problem with the engine's imobilizer
contact may be a mechanical problem (the key is too worn out and old)

2001 Taurus won't turn over and PATS light flashes all the time

The beginning of your problem sounds fuel related (relay, fuel pump, fuel filter). The Ford ECU never goes bad, they are the most reliable on the market. Also ford has a low oil shut down, make sure oil level is correct. Get a OBD II diagnostic test to check for faults stored. When replacing parts start with cheapest first. You were vague on the cranking problem. Not turning over and not cranking are two different problems.

I have a 1997 Bonneville. The dash boad lights come on and all lights and turn signals, but nothing when I try to turn it over. I have checked the battery its good, the key and its chip is good or the key...

This was a common problem with the passlock security system. I have a 92 firebird that did the same thing, you can find how to fix it on youtube actually. There are two wires coming from the ignition switch that you can splice in resistors to bypass the security system. It is a really cheap, cheap, cheap fix. I hope this helps.

Broken key from hot ignition??

I can think of two possible problems you might be having. One if you said you actually broke the key, if the key is really broken it might have an anti theft device and it such as a resistor or possibly a chip and if the key is damaged this could cause more resistance causing the key heat up. And if the ignition switches is located close to the keys cylinder you might have bad contacts at the switch or bad connection where the harness connects to the switch heating up this whole area and the key. Good luck.

The key has a micro chip in it that transmits a signal/code to the anti-theft module/immobilizer. There have been cases where the immobiler/module has forgotten wht code it should respond to or the chip in the key has gone bad. Either way the vehicle will have to go to the dealer for repair as they will have to reprogram the immobilizer for the new key and vice versa depending on which of the 2 items went bad. Hope this helps u

Security problem

I can't really send you the information on how to bypass the antitheft system. It would be defeating the purpose of the antitheft for everyone else that has it in thier car. But. You have a couple of choices. Bring the car to a dealer and have them fix it properly or, bring it to a car audio/electronics place that installs remote car starters and have them bypass the antitheft (probably cheaper option).
On your key there should be a black square with a silver piece in the center. That's the antitheft part. Check to see if its clean and not worn down. Or the contacts inside the key cylinder (ignition) could be worn down, if so, it needs to be replaced. When starting wiggle the key abit, it may take a few tries because of the 'timing' of when the antitheft system actually 'checks' the key.
You can get a new key made by a place that knows about the chip in the key, it's not exactly new technology so most places that can make keys should know about it. I suppose you could also hit the steering wheel repeatidly at the same time that your turning the key while your trying to start the vehicle. But you probably did that by now in frustration.
If there's no black square with silver piece in the key then there's some type of aftermarket antitheft system that's malfunctioning.
