Toyota Camry: 94 Camry Starting

I have recently encountered a problem with my 1994 Camry LE.

1. Sometimes (about 1/3 or 1/4 of my starts, I would say), I turn the key, and
nothing happens. Usually, I turn the key again, and it starts.

Once it took a lo-o-o-ong time, and many tries, but it started.

Can anyone tell me what is happening, and whether I should take it to a shop to
be fixed?

2. About the same time, the key developed another problem, which is just a
small annoyance. Most times, the key will not open all doors, just the one
that I am using it in. (It requires two turns to open all doors with the
driver's door, but one turn with the passenger door.)

Thank you in advance for any advice you can give.

My 99 Camry was clicking and not starting all the time. It would
disengage some times while cranking too. The battery was new and
connections clean, so I suspected the starter was bad as it has 190K
miles and is started many times per day. It would start if you tried
it many times but soon I knew I would get stranded. I researched it on
the net and found out that the contacts in the starter solenoid (on
the starter), wear and lose good contact. This is a major failure
point for the Toyoyta starters. They are replaceable ($20 or so), but
given all the miles on mine, I opted for a rebuiit starter from a
foregn auto parts store for about $175. The dealer wanted $400 for a
new one.

BTW, it is only 2 bolts to remove the starter on my (4 cyl) engine
after removing the air cleaner box for access. Very easy to do in 1/2
hour. It solved the problem. I took the old starter apart before
turning it in and one copper contact was badly worn by the solenoid
plunger - it looked like it was machined in a lathe! So, I am sure
that was the whole problem with mine.
