I have two keys for my 2009 Dodge Caliber, but one has stopped starting the vehicle -- it can unlock/lock doors, but will not start the vehicle. Any ideas?
Have you tried a new battery? If you di and the issue remains the remote is likely defetive.
Testimonial: "I swapped batteries with the key that worked... no dice. Is my key bad?"

fob broken or bad, or fob battery bad, key problem not reading key code

I just found out that in the 2008 year model the sensor mondular for the keyless remote has a tendency to attract static electicity and that leads to shorting out causing the vehicle not to start unless you disconnect the battery to reset the computer. The tech installed a new sensor module that is supposed to have the flaws corrected. I guess we will see if it does and if this is truely the problem at hand. I do want to comment on my 2008 caliber. I am honestly happy with it.

This means that the programming of the Transponder Key has been corrupted or the Programming data of the Key in ECU ( Electric Control Unit ) has been lost or not responding. You now have to get a new Transponder Key. You can get it on E-bay for $30. After you receive it, reprogram the car to the New Transponder Key to the ECU ( the process in usually given in the instruction manual or in the Service Manual ). Then the car will start perfectly.

theres a tech bullitin on that make where computer needs reprograming for the door locks, but it also sounds like you may have a bad actuator lock thats bad, start there call your dealer first and ask them about the reflashing of the computer for the door locks, good luck.

Check with dealer on technical service bulletin, and/or recall regarding this. My Daughter had same problem, it was to do with sensor in ignition for recognizing key.
Have heard some say, reducing static before putting key in also helps, such as rubbing hand across metal roof or door post prior to inserting key. Dealer stated it's to do with radio frequencies interrupting signal, but they don't sound 100% sure on that either , but apparently new part is less, or not as sensitive.

Valet key (gray plastic end) which can start the vehicle and unlock/lock all doors, but can not unlock/lock the storage compartments, or rear compartment lid lock.
Important: The transponder values are not readable and can not be serviced separately.
Theft Deterrent Module
The theft deterrent module contains the software for controlling the VTD System. The theft deterrent module uses the following inputs and outputs to control the VTD system.
Inputs
?€¢
Battery voltage from the underhood fuse block PCM/BATT fuse, circuit 240 (ORN).
?€¢
Ignition start voltage from the ignition switch, circuit 1390 (WHT).
?€¢
Ground, circuit 450 (BLK).
Outputs
Password exchange with the PCM (fuel enable), class 2 message circuit 1807 (PPL).
Powertrain Control Module (PCM)
The PCM verifies that the passwords received from the theft deterrent module via the class 2 serial data line are valid. If a password is invalid the PCM disables the fuel delivery system. If the password is valid the PCM enables the fuel delivery system.
Starter Relay
The starter relay is controlled by the PCM module via class 2 serial data (CKT 1807 PPL). If the theft deterrent module measures the correct transponder value, the PCM module switches the starter enable control (CKT 447 YEL) to ground. The relay is energized if the ignition switch is in the START position and the gear selector is in the PARK or NEUTRAL positions.
