I lost power to my car and when I replaced the battery the enter password screen come up. According to the manual I entered the wrong password in 3 times and that caused the touchpad to be disabled and to grey out the touchpad keys. Does any know how to re-enable the touchpad on it so I can try the password again

Wait 10 minutes.

Make sure the parking brake is pulled.  For security reasons, the keypad will be disabled if it isn't.

I just took the key out, waited a sec, and put it back in.  Three more tries. Did it over and over, never waited 10mins.  Maybe make sure the key is far enough from the ignition when u remove it that the transponder doesn't pick it up.  Doubt that matters though. I was parked and do always use parking break so above post right as well probably.
