I put a new ignition switch in my 2004 chrystlwr pacifica but it still wont start, how do i program rhe ignition switch?
ANSWER : Hello.

If your vehicle is not cranking, but the lights and accessories come on then it may be possible that the issue is rooted elsewhere. I would verify that the starting and electrical system are in good order. A no crank condition can be caused by a faulty battery, starter, starter solenoid, relay, or any of the wiring associated with these components. I would start with checking the battery and starter, and go from there. If you wish to program your new switch and key, the procedure is as follows:

Note: You must have two valid keys to add a new key to the system.

Insert the first valid key into the ignition switch. Turn the ignition switch to the ON/RUN position for at least three seconds, but no longer than 15 seconds. Then, Turn the ignition switch to the LOCK position and remove the first key.
Insert the second valid key into the ignition switch. Turn the ignition switch to the ON/RUN position within 15 seconds. After 10 seconds, a chime will sound. In addition, the vehicle security light will begin to flash. Turn the ignition switch to the lock position and remove the second key.
Insert the new key into the ignition switch. Turn the ignition switch to the ON/RUN position. Within 60 seconds. After 10 seconds, a single chime will sound. In addition, the Vehicle Security Light will stop flashing. To indicate that programming is complete, the Vehicle Security Light will turn on again for seconds and then turn off.

The new key is now programmed. The Remote Keyless Entry transmitter will also be programmed during this procedure.

Repeat this procedure to program up to eight keys.

If you need some assistance with this, consider YourMechanic, as one of our certified technicians can diagnose the starting issue firsthand and perform this procedure as necessary.

ANSWER : Hello. If your vehicle is not cranking, then I would first verify that the starter and electrical system are functioning correctly. Aside from a bad ignition switch, a few common causes for a no crank condition are a faulty starter, starter solenoid, starter relay, or bad wiring. If you replaced the switch, and wish to program the new keys the procedure is as follows:

Got a new ignition switch, car starts now but believe it’s faulty. Can a bad ignition switch damage the catalytic converter?
ANSWER : Hi There,
The catalytic converter is entirely unrelated to the ignition switch and neither of these should impact the other. The catalytic converter converts toxic exhaust gases into less harmful pollutants that are suitable to be expelled into the atmosphere. When the catalytic converter is clogged, this causes these gases to be backed up into the exhaust system not allowing the engine to breathe properly. When this happens, the engine is forced to work much harder to expel these gases. This often results in the engine bogging down, hesitating, shaking and causing very poor fuel economy. This should also cause a check engine light to come on as the O2 sensors should be reading the incorrect amounts of oxygen in the exhaust gases if this is your problem. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your catalytic converter.

I changed ignition starter switch, it cranked then die again. Fuel pump is not coming on. Could it be the ignition switch itself?
ANSWER : The ignition switch turn on circuits to supply power to the vehicle, but does not control the fuel pump itself. If your vehicle is equipped with a fuel filter, it can clog and cause the fuel pump to work harder eventually burning it out. Have a technician check for supply voltage at the fuel pump and check fuel pressure. If there is power going to the pump and no fuel pressure, replace the fuel pump. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your stalling concerns and offer a more personal diagnosis.

If I replace the ignition switch, can I use my existing BMW Keys with remote and valet key?
ANSWER : Yes, you can. The ignition switch is separate from the EWS system, so replacing the switch will still allow you to use the current keys you already have. Only if you have to replace a faulty key or EWS module will you have to possibly order all new keys.

One other possibility is there is an EWS issue where the key is not being properly identified not allowing the starting sequence. This would mean ordering an EWS module or keys from the dealer. Try out all keys you have to see if any will commence in the starting sequence. If none of the keys will start the vehicle, faults should be checked to ensure there are no EWS key identification faults. If no faults are present, then most likely the ignition switch is faulty. If there are key identification faults, then it’s either a key, module, or receiver that is the issue. You may want to consult with a mechanic who has the equipment to read out the Powertrain and EWS fault memories before replacing parts.

My car won’t go past 35mph
ANSWER : Hi there. From the description you provided, your vehicle has problems with the transmission again. You stated it will not shift into 3rd gear again, like before the transmission was rebuilt. If the transmission is again the problem, it should be covered under warranty. It could be a faulty shift solenoid. The shift indicator not reading properly could be a faulty transmission position sensor. If this is an overall lack of performance issue, according to your last statement, then possibly you have a restriction in the exhaust system. I recommend having your vehicle’s problems inspected and diagnosed by a certified technician from YourMechanic.
