The most common problem with these car key fobs is that the batteries just go dead over time, in which case replacing the battery should fix the problem. Check and replace the key fob battery as needed.
Take the key fob apart and check for broken contacts or misaligned buttons…. Try holding the fob right next to the door handle when pressing the unlock button. If it unlocks the door, the problem may be a weak battery in the key fob, or a problem in the keyless entry antenna or wiring. The key fob itself could be defective or have a bad unlock button. Another reason that your car keys might not be working might be because the batteries in your key fob or keyless entry remote are out of juice.
When you do realize that your car key is not working because of worn out key fob batteries, the simple solution is to find the right batteries and then replace them….
An inoperative power door lock can be caused by the switch, solenoid, wiring problem or mechanical problem within the linkage of the affected door. If all of the door locks are inoperative, start your diagnosis at the fuse box. Inspect the fuse that protects the door lock circuit to ensure it is not blown.

The bottom cover has 3 philips screws, one at very bottom, two behind steering wheel turn wheel sideways. The top cover has one screw going up near the cylinder you access after you remove the bottom cover. One more screw holds the black key detection ring around the lock cylinder.
Why don't you just copy the valet key and keep the original at home, using the copy for daily driving? If you lose the copy, you still have the original you can copy. I also wouldn't use duct tape in a car. Cars experience high levels of humidity, drying, moisture accumulation, condensation, extreme heat, extreme cold, and vibration which will eventually deteriorate the adhesive on many adhesive tapes. If you must attach something inside your car using an adhesive, use a permanent one which is resistant to the elements I listed.
Household adhesive tapes fall apart very quickly inside a car. If it was my car I would replace the immobilizer ECU and make a new master key, but this was a customers car for a family on a limited budget. This was the best solution for them since multiple people share the car. One is proximity sensor based where the fob has to be inserted into the dash, this starts the car via an RFID chip and does not require a battery. The 2nd system full SKS just requires the fob just to be inside the car and a healthy battery in the fob.
However, the full SKS system doesn't like you leaving fobs in the car, it may prevent you from locking the doors. What exactly do you want to accomplish? It is only an RFID proximity based system and the key needs to be fairly close to the detection ring. Think of the detection ring as the antenna for the system, the ECU is just the electronics.
I have a steering column from a wrecked that I would like to put in my son's that came with only a "valet" key. Can I just plug the transponder ring from '03 column into the harness of the '01, or do I have to use the '03 "ecm immobilizer" also?
I pulled the immobilizer out after removing the new collumn. Even with the column out it was a chore to unbolt then unplug the immobilizer from the harness. Is there an easier way? Thanks for your insight.
