Locked key in car
In an absent-minded moment while doing some troubleshooting, I managed to lock my keys in the car. The car is off the street in a secure area, and I don't need it to drive, so I can afford to take my time with the least "invasive" method of basically breaking in.
I've read about basically yanking on the hatch until the receiver breaks, or taking out one of the curved hatch side windows, but if I can be even less damaging than that, even better. My door locks are already shot (I had to open the hatch and reach in to lock/unlock the car with the internal knob, hence part of why I didn't realize I left the keys in), so if there's a way through there, I'm especially interested since I'm going to have to re-key eventually anyway.
The lock tool pictured in the Porsche manual page needs to be made from some seriously stiff wire, as Jim B points out. So a reformed coat-hanger won't get the job done. I happen to like arc-welding rod, with the flux removed with a wire brush, since it tends to be pretty darn stiff. You can usually get a "sample" piece at a welding supply store if you don't have such things in your DIY arsenal.
Of particular interest in the picture is that the loop is inserted behind the lock (towards the rear of the car), where the common assault would be from forward, where glass flex would leave more room to get the tool in next to the molding.
Did this the first couple weeks I owned mine as the doors wouldn't stay open and I had taken the door panel off to fix a bad window motor and inadvertently put the lock down.
I tried the above with the tool with no luck as the protection plates were still over locks and the insertion of that tool has to be very precise.
Had a locksmith try for over two hours and he said that the 928 was a virtual armored car when it comes to breaking into them. The two that he had dealt with in the past both had their locks slide hammered out when stolen.
Ended up just breaking the passenger side quarter panel glass, they are cheap and I sourced one locally before breaking the glass. It takes longer to vacuum up and remove the broken glass then it does to install a new one.
Good luck and I hope you are successful!!
Grab the bottom lip of the hatch with your finger tips (right under the lock) and pull on it really hard. There is a good chance the hatch will pop open, it does on many 928s that have a slightly worn hatch lock mechanism.
ps: or use one of these inflatable wedges:
Just went through same thing two weeks ago, but my car was in a local parking lot on a Sunday, night.....after 4 hours and 2 local locksmith attempting to use their own style Porsche Tool, a third locksmith who I though was not going to come, showed up just before I started in on the rear quarter as the car was NOT staying in this lot over night.
After he gave me all his assurances he could get in without damaging the door frame and info on insurance, bonding.....he was in, in less than 5 minutes using (2) of the larger inflatable bag deals, to be honest I almost stopped him cause I was terrified what it would do to the door frame. End of the day he got in super quick and easy for him, charged me $65 bucks and made me a spare key for $75 the next day.
The other (2) locksmiths wear sitting watching this guy......
On the day I sold my 86.5 I inadvertently locked ALL of the keys in the car. After many hours, we finally snagged a key using a locksmith's small inflatable bags (inflating them incrementally) at the top corner of the driver side door and reaching in with a LONG tool. The paint did not go untouched, but it wasn't too bad. In retrospect, if we had used the inflatable bags (same technique) on the rear hatch lock I have no doubt the hatch would have popped open in short order with little to any effort.
Or make an opening in the floor panel. The metal disc that you push up in the floor just goes back down...seal with any caulk you prefer and cover with the floor mat.
One more way is to try with a string and a slip knot (a loop that closes when you pull hard on both sides of the string.
