The reason for the subject mentioned question was because today, upon attempting to enter my '03 Taurus wagon, I did as I always do and pressed the unlock button on the remote... but, for the first time ever, it wouldn't open the car. Suspecting a dead battery in the remote, I went back into Walmart to get a pack of 2032 batteries and replaced the one in the remote. Nothing happened, so my next suspicion was maybe corrosion between the terminals and battery, so I disassembled and carefully used a knife to scrape at the terminals the best I could but it wasn't very effective. However, the car then opened by the remote. When I got home, I took a box cutter knife and did my best to scrape the battery terminals further. It seemed to help and the remote now works like it did before. However.....
Not being so sure this might not happen again, I searched all over for the key to open the doors. All I could find was a spare attached to an extra remote, but all that did was start the car. The question is: Is there supposed to be two keys with my car, or is the starting key and remote all that I'm supposed to have? I inherited the car, so I'm not sure. I would like to get a key for the doors if possible so I'm not locked out again.
