first car with push button keyless entry (or heck any kind of keyless entry). How long do these batteries usually last?
Depends on the quality of the battery in there, 1 to 2 years usually by my experiences. Most of these batteries are user-replaceable, and generally just a simple watch battery. If you ever have to replace, do yourself a favor and replace with a name brand so that they last longer.
Can you ever be locked out of your car, or not be able to start one with dead batteries?
Check your owner's manual, but as others have mentioned, there's usually:
- A physical key you can slide out of the smart key to unlock the doors.
- A way to either use that physical key to start the engine, or some other method to start the car with a dead smart key. Sometimes the smart key has a slot to stick it into, sometimes you have to dump the key in a cupholder, sometimes you push the ignition button with one end of the key, etc.
- Most smart key systems will not let you lock the keys in the car or trunk,
initially. However, some cars have an emergency failsafe where if you try locking the keys in multiple times, the car will assume you want to do this and actually lock the doors with the keys in after multiple attempts.
Therefore, I highly recommend you learn what the car does when it tries to tell you it won't lock due to the keys being in the car (usually some kind of weird beep), because if you don't realize this and your car has the failsafe you can lock them in pushing the lock button multiple times, thinking they're in your pocket when they are actually in your jacket in the car or something.

That black on that 300 really shines. Looks good man.
Thanks, it was desperately overdue. Unfortunately, there's still some visible spiderwebbing from whatever the previous owner did (automatic washes I assume), so in 5-6 months when it's time to re-do this I'm going to look into paint correction.
