It sounds like the anti theft pass key's have most it's memory and needs to be reset. Try this, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help

Multi function switch ( signal switch assembly ) is bad .. most part stores carry after market now and they really aren't that hard to change. I would expect around $200.00 for the part and 1.5 hours to change. If you are fairly handy you could pick one up at a salvage yard and change it yourself and save quite a bit.Once you remove the plastic column cover and the tilt lever ( it pulls straight out ) there is one screw holding the bottom that you will need a torx bit and a 1/4 drive wrench to remove so you don't have to pull the steering wheel.
Hope this helps.
