I purchased a used Z4 and it came with three keys. I understand the keys
need to be used in order to "charge up." Once they discharge they will no
longer work.

I had a basic OEM alarm put in the car. Two of the keys activate the alarm
but the third neither activates the alarm or remote door lock/trunk
functions. I hope it is something as simple as not having a substantial
charge (it can be used to manually open the doors and start the car).

Any ideas?

From http://www.answers.com/topic/key

"Some cars come with an additional key known as a valet key that starts the
ignition and opens the drivers side door but prevents the valet from gaining
access to valuables that are located in the trunk or the glove box."

Does that sound like what you're describing?

No. It has the frequency indication on the back of the key and it opens
the trunk. I am going to use it for a while and see if charging it up will
help but I think it is bad.

The valet key is a little black plastic key. Not like the other (fob
type) keys.

The valet key is *NOT* the black plastic *WALLET* key. The
valet key has no fob, and if used won't let the trunk open, etc.
The wallet key is full-fledged, even though it doesn't have the remote
features.

use it for a day and it should charge up while in ignition.
