I'm going to trade my chip in for the JC chip in the near future. I was worried that my car was going to collect dust in the garage while I waited for my new chip to arrive.... Then while sorting through some maint records from prior owner, found the original chip!! It's wrapped in a plastic bag along with Dinan papers and instructions. Can I simply pop it back in the car or do I need to clean it with something first? I'm edgy about handling these things, any advice will be helpful.
