Key entry not operating

[Ubuster1]

I recently became an owner of a 2004 boxster base 64k miles 5 speed. The door key isn’t working open and locking is done strictly with the key. This could be a future problem if battery should ever die. Over the winter I am going to do the repair. Currently the key toggles left to right with no restriction and you think it would work but doesn’t. Can anyone suggest what parts could be required to do the job.

Welcome to RennTech 

I will assume that when you say that opening is done with the key that you mean it is done using the buttons.  If that is the case, the immobilizer is working, but not the key.  Probably at some point, either the door or the door's lock was changed, which is why it no longer matches the key.  Unfortunately, the answer for this is going to be pricey, as in order for the key to work the door, the immobilizer, and the ignition, you will probably end up having to replace the door and ignition locks, keys, and reprogram the car to accept the new keys.

Your correct the buttons on the key remote are used to unlock and lock along with trunks are working fine. The Key starts ignition fine but it won’t open the door. 
Thank you JFP.

The car's keys should match the ignition and door lock mechanically, and the obviously do not.  Problem is that Porsche uses a very unusual key type, so I do not think re-keying the door lock is a practical approach, and you will end up replacing both locks to get everything to match.

If the key fits in the lock cylinder and you can turn both left and right, but it feels loose, without any resistance than the circled part in the pic. is probably broken or badly replaced after a previous intervention.

Can the front hood be popped and left unlocked over the winter months Or will it kill the battery?

It doesn't need to be left open, simply buy a quality battery maintainer like Ctek, plug it into your cigarette lighter socket, run the cord out thru the cut out in the bottom of the driver's door (there for this exact purpose), and let the car sit for months (locked with the alarm on) without any issues.

Is this the flap under driver door your speaking of to run feed?
Thank you John
