This can pose a problem if the keyless entry transmitter is damaged, lost, or inoperative for any reason while you attempt to disarm the content theft deterrent system.
Mode 1: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter. The system does not arm when you lock the doors with a power door lock switch.

Mode 2: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the doors with the keyless entry transmitter. The system does not disarm when you unlock the doors with the key.

Mode 3: The system arms when you lock the doors using a power door lock switch or the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter.

Yes they are related. Sounds like you need a new lock cylinder and possibly a new lock solenoid.

I would start with getting a new key and having it programed which means a trip to the dealer.

Ck fuses? Maybe horn went bad?!!

I had the same problem with my 2007 Sahara Unlimited. I'll make a long story as short as possible. For a number of years my son ran a Chrysler / Jeep dealership and I contacted him (I bought my Jeep from him before he got out of the business) and he told me this is a sporadic problem with the Wrangler line. To the point of calling him I had tried everything and nothing worked...insert key, turn, nothing...all electrical worked, lights, power windows, radio, etc, etc. He told me to disconnect the negative power connection on the battery for a second or two then re-attach. Insert key, engine starts, everything works as advertised.

Essentially, my son told me this "re-boots" the system. For whatever, and to his knowledge, never explained by Jeep, this fix works but no idea as to why it happens in the first place.

Hope this is of some help...though I suggest that there may be more "fixes" to this problem.

Regards...

TRY THIS:
Sit inside the vehicle with all the doors closed.
Place ignition in the OFF position.
Open the driver's door. Leave Open.
Move the mechanical door lever to the LOCK position.
Turn the ignition to the RUN position.
Aim the transmitter at the Keyless Entry receiver and press Lock button.
Hold for five seconds until the door locks cycle.
Turn ignition OFF within 20 seconds

Good luck and hope this helps

TS06 DEC 05 Keyless Entry - Transmitter(s) Inoperative

There was a recall in DEC. 05 for this particular vehicles remote transmitter system....though im not sure if they would do service free of charge now...

Moving along...if you have no working transmitter, you have to do the following to get it working again:

* Ensure vehicle audio PIN number is known or audio PIN security system is deactivated prior to battery disconnection.
* Ensure a door is open
* Disconnect the negative battery cable, wait minimum 5 seconds then reconnect
* Within 20 seconds of reconnecting the battery cable, insert the keyin ignition then cycle the ignition key from the "ACC" position to the"ON" position 20 times, leaving the key in the "OFF" position after thetwentieth turn.
* the vehicle's indicators will flash 20 times to indicate successfulentry. NOTE: Should the indicators fail to flash, wait 5 seconds thenquickly turn the ignition switch from the "ACC" to "ON" position 10times, leave the ignition "OFF" after the 10th turn and wait 15 secondsthen recycle the ignition switch 20 times.
* the vehicle's indicators will flash 20 times to indicate successful entry.
* within 10 seconds of the indicators having ceased flashing, press the button once on each transmitter.
* turn the ignition key to the "ON" position to lock in and exit from the programming mode.

And if you have even 1 transmitter that does work, its not nearly as difficult:

* ensure a door is open
* remove key from ignition
* lock the doors using the transmitter
* unlock the doors using the transmitter

Within 20 seconds of unlocking, insert key in ignition, turn theignition key from the "ACC" position to the "ON" position 20 times,leaving the key in the "OFF" position after the twentieth turn.

The vehicle's indicators will flash 20 times to indicate successful entry.

Within 10 seconds of the indicators having ceased flashing, press thebutton once on each transmitter. Once finished, turn the ignition keyto the "ON" position to lock in and exit from the programming mode.

Hope this helped,
Jem
