Ok...

So I was at Advanced Auto Parts... and they have this display.

It said - test your remote key's battery power.

So I tested my Lexus Key.

And the battery in it was good.

Then I tested my Mas key.

And the display said that it had ZERO battery power.

And so I look at my key - and there's not even a screw to replace a battery if there WAS one in the key.

Not for anything else but curriosity sake...

But what kind of key is this?

Does it even have a battery in it?

Yes it has a battery, as I recall 2. You just gently pry the 2 halves apart and you will see them.

Does the battery in the key recharge while it is in the ignition as to avoid replacing the battery? I think my BMW key does that...

My spare key is dead and the main one needs to be shaken every once in a while for it to work. How much is a new one??

Open it up and clean the contacts, then replace the batteries, that should do the trick.

I just paid $300 for a new key. I now get to pay an hour labor to have it programmed to the car.

I'd replace the battery if I were you. ;)

As far as the spare key... mine is maroon and it has a black button on top.

Maybe the battery is dead on it? But what does that black button do if anyone knows...

Your key won't lose the programming if the battery goes dead..

Just replace the battery's, it takes two, you can pick them up at any Walgreens.
