When I push the unlock button on the door or the fob it unlocks and then locks back. And then when opening the door is almost like the wire inside is too long but it's never been replaced, can it get stretched out?

I've noticed a rather loud clicking noise coming from both the passenger and driver side. It sounds like it is either coming from the door or under the dash. Noise persists when radio is off. It seems to cease once I go around 50mph. The sound is random, woth no particular pattern. No warning lights are on. It sounds like it may be something electrical. What could this be?

Brand new spark plugs and spark plug wires. No weird sounds. No security issues.

Tried to shift into reverse, but won't shift back to reverse or park from neutral

I bought my car about a year ago. Ran great until one day heading home everything lost power and it died. Got new battery and alternator. Six months later, here we are again. Last time though, it died and I couldn't restart it period. Today, battery light came on, everything dimmed, pulled up to a stoplight and it died. 5 minutes later it restarted and drove it 2 miles and it did it again. Because I can restart it, i'm hoping its not the alternator? HELP?!?!?!
