Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello I'm Neal and I am here to help resolve your issue. If I cannot help I will opt out and refer your question to another expert.
If your spare is working normally, then it is just going to be the way your key is wearing most likely. A locksmith can usually "tune it up" and make it work again or make another based on your spare.
It is also possible your key was damaged or bent, so check it closely.
