The RKEM (remote keyless entry module) is the problem.
Only a DRB-III scanner can program the transmitter codes and VIN number to remedy this problem....I hope this helps.

The PCM -engine computer energizes the cooling fan relays , hi an low speed , according to information received from the coolant temp. sensor. an information programmed into the PCM . Usually around 221 degrees the PCM will energize the low speed relay . Is your car's temp . getting that high ? The best way to diagnose these types of problems is by hooking up a scan tool that can read engine sensor data parameters to see what the temp. of the engine is . Also a scan tool with bi-directional controls , this would be useful to see if the PCM can control the fans ! There could be DTC'S - diagnostic trouble codes stored in the PCM . Not all DTC'S turn on the MIL light , check engine etc..

The relay is grounded by the computer when the temperature sending unit sends a signal to let it know the fan needs to come on. The relay needs 2 power sources. One will have battery voltage at all times ( possibly the one you are jumping ) and another pin will have batttery voltage with the key in the on position only. If either power source is missing, the fan will not operate

Although you have not shared the mileage on this car, I am suspecting it needs transmission service. I could say this will fix it, but honesty says it "might" fix it. I suggest you have the fluid and filter changed. Unfortunately, many shops today want you to do a "transmission flush". I say no. Be very cautious, and ask around for an honest place. There are many that will cheat you. Some will even take your transmission all apart to "check it out" , and will not reassemble it unless you pay hundreds or thousands of dollars.

The timing belt, water pump, tensioner and idler pulleys are all behind the timing cover. You'll need to remove the cover and visually inspect the components under it to figure out what is making the noise.

you'll need to remove the timing cover and take a look. It could be the timing belt slapping the cover or the water pump going bad or even a bad tensioner or idler pulley. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

It may be the timing chain/belt assembly.

Get it on a lift and check the engine mounts, exhaust and then under the hood for loose trunking etc. Look for shiny marks on hoses etc to denote rubbing on something.

I had same problem kept hitting panic button several times and it eventually shut off. Never found out why alarm started on it own.

check the battery and make sure it has a fully charge,also check to make sure the start motor pinion is not jammed in the flywheel, and check the coil pack to make sure have spark.also check the crank sensor

Owners manual will give fuse locations and identification. Most fuses for accessories are located under the hood in the fuse/relay panel.

The PT cruiser uses a field signal from the PCM to regulate the voltage. If you are not getting approximately 14 volts at the battery terminals when the engine is running, either:

1. The replacement alternator is faulty.
2. The generator field control signal from the PCM is faulty.
3. The Fusible Link between the alternator and the Starter Motor (which is also the same electrical point as the battery positive terminal is open.

Use the diagram below and check the alternator output at the point labeled "A11 6 BK/GY" If this is 14 volts and there is not 14 volts at the battery terminals, then the Fusible link is bad. If there is no voltage or way less than 15 volts at the alternator, then the alternator or the PCM field signal is bad. Ensure the connector from the PCM is connected properly.

belt is not in the right place you must alien the timing marks on both cams and the crank

Bad relays or temperature sensor or fans. Most likely temp sensor

Check for extra gaskets or spacers in the wrong place...is this a replacement housing or stock? Also be sure you turn the lamp for proper sealing and fit in the housing...

Does the vehicle turn off, run rough, or hesitate?It sounds as though you have a faulty Idle Air Control Valve".
