Hello, thank you for writing in. A battery inspection is a great place to start. You can remove it and have it tested, attempt to jump start the vehicle, or test the battery in the vehicle with a voltmeter if equipped. The two systems are both wired to the starter solenoid which them amplifies the amount of available energy and cranks over the starter. The key not moving seems like the entire starting system is incapable of being switched on. This is most likely an electrical issue which steers you towards the battery, wiring, starter fuse/relay, and the security system. Further testing will need to be done. For assistance testing the battery and starting system, contact our service department to schedule an appointment.

Engine turned off but inside of car still on, now engine won’t turn back on.
ANSWER : Hi there. The symptoms you’re describing with your boyfriend’s 2002 Grand Cherokee appear to be related to a broken or worn out ignition switch or relay. The ignition switch on the inside of the steering column is attached to multiple electronic connections that send signals to a relay box; which in turn, sends the signal to the individual components. The issue could be related to the ignition switch, the relay, or any of the components in between. If you want to have the fault pinpointed in person, I would have this starting issue inspected by a trained professional to ensure that the correct repair is made.

Put key in ignition. Lights and everything come on for a second, then went off as I turned the key. Now no power, key stuck
ANSWER : Hi, thanks for writing in. This sounds like your battery cable connections are corroded or loose at the battery. Try to see if the battery connections are loose by wiggling them and see if power returns. If power returns, then have the cables removed, cleaned, and reconnected to test the battery. Hope this helps and best of luck!

ANSWER : Hello and thank you for contacting YourMechanic. There is a rubbery stick substance that is inside the ignition switch to protect the key as it is inserted. What seems to happen is the ignition switch got hot and melted the rubbery stick substance. The fix to this is replacing the ignition switch for it to got hot and failed. Also, check the wiring to the ignition for any loose or damaged wires. If you need further assistance with the ignition switch, then seek out a technician, such as one from YourMechanic to help resolve this problem for you.

car sat for 14 days, key stuck in ignition won’t turn over, new battery doesn’t help
ANSWER : Many different items can cause the vehicle to not start. With the key stuck in the ignition it is possible there is a ignition switch or key cylinder fault. For the no start, the most common causes are the ignition switch, battery, starter, fuel pump or battery cable. I recommend having a qualified mechanic, such as one from YourMechanic, come to your home or office to inspect your no-start condition and make the correct repair.

steering wheel won’t unlock my key turns only to turn lights on but that’s it can’t unlock steering wheel to start the car what to
ANSWER : The steering lock may not be unlocking either due to a faulty ignition lock housing or more commonly as the cars age a faulty spring at the steering wheel on the under side of the column. If the ignition lock housing is the issue the housing can be replaced. It s a bit tricky as the mounting bolt has break off heads and generally need to be driven out with a punch. If the lock is not disengaging because of a faulty spring on the ignition lock many owners have had the spring removed by having it drilled out of the housing. However, removing the spring may permanently disable the steering lock. The last option would be to replace the steering column. You may want to enlist the help of a mechanic who can recommend the proper repair for your situation.

As I’m driving, all my lights inside/out of the car turn off and the car still stays on. But when I turn the car off it won’t turn over
ANSWER : Hello there. The charging system on the car may not be charging the battery as you drive and the systems that keep the engine running are priority so the engine will stay running until the voltage drops below about 9 volts but the lighting and some other accessories may cut off above this voltage first. You should have the charging system tested to see if the alternator needs to be replaced.

The smart key can turn the ignition but can’t start the car
ANSWER : Hi there. It appears that the issues you’re experiencing may be caused by the ignition lock cylinder. In some newer vehicles (made after 2000) this part has multiple springs inside the cylinder that allows you to press the key forward and allow it to automatically spring back once the vehicle starts. If this is not happening, then I suggest having a professional mechanic diagnose the starting problem so that the ignition and starting issue can be addressed properly.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
