Remote key and other problems, Help

[torin03]

I recently bought a 2001 Boxster, the car was not used for months since it was wrecked. The original battery was never removed and when the car was fixed the car was replaced with a new battery since the original battery was damage. Now I face the following problems:

1) Remote key was also replace with new battery since the one it had did not work. The Remote does not work, the red light does blink quickly but does not open doors nor hood or trunk. Car alarm does not go off too.

2) The power windows don't lower down when pressing the window bottons, but when the doors are open, the windows do lower about half of inch.

The fuses were checked and apperently all of them work.

Please help if someone knows how to fixed these problems.
