997.2 Ignition Switch Replacement

Instructor
Thanks for this important clarification. I was thinking that the replacement lock must to be "matched" by the dealer in order to "mechanically" work with a particular key (aside from the transponder). Now I understand that the engraved keys are only for use with the door lock (with 997s should be just one, as it doesn't have key lock in passenger's door). Good to know this little detail certainly.

I just wanted to say thanks for all the helpful contributions to this thread - I replaced the switch in my 987.2 today.
Regarding part numbers, my 987.2 was fitted with 99761815904. I replaced it with 99761815903 (from a breaker) and all seems to work fine.

Needed to tackle this job tonight.
Background - 2009 C2S PDK 70k miles. I managed to kill the battery. Used the small post in the fuse box to apply voltage and pop the frunk to access the battery. No issues. However after that I could no longer remove the key from the ignition as has been described in this thread. Used the small wire hook in the cover of the fuse box to manually release the key. Ordered new ignition switch.
The replacement of the ignition switch was very straightforward thanks to this thread! I managed it in less than 10min using the tools in the photo. This job is made SIGNIFICANTLY easier if you can cut the zip tie safely. Once cut the wiring loom is long enough to reach out the back of the lower dash where there's plenty of room to get two hands on the ignition switch and connector. Once I got the old switch out following the directions in this thread, I used a long, thin, non-serrated slicing knife to cut the zip tie. For me the bulky part of the zip tie was on top allowing me to very carefuly go through the ignition hole keeping the knife parallel to the wiring loom and sniping off the head of the zip tie. I used the small hook tool to pull and hold the new ignition switch into place and hold it there while I screwed the collar in place to secure the new switch. Whether you use a knife or screw driver or snipers somehow, cutting that ziptie is key. Just have to be very careful to only cut the ziptie. If you wanted its possible to use a new ziptie to re-secure that length of loom but honestly I didn't see the need.
Hope that helps someone.

I've had a weird engine stall/no-start issue happen to me twice that I think may be ignition switch related
Symptom:
First-time: Start car after it was in garage for 1-week, no problem. Drive for ~ 1 hour, then stop at grocery store. Come back out, start car, drive 50ft and engine died (thought I may have stalled it). Attempt to restart engine (turn key from "on" to "start"), nothing. No starter engagement, nothing. With key in ignition switch, push car to parking spot, and remove key. After 30sec of cussing. Thought I'd try to start it one more time before calling flat-bed. BAM, engine starts normally (starts instantly, no slow start like when battery is going bad) and I drive back home.
Second-time: Similar scenario. Car starts fine after sitting for 1-week. Drive for 1-hour and stop for lunch. Come back out, start car, drive 50ft and engine dies. Attempt to re-start engine by turning key from "on" to "start" Nothing! Turn key to "off", the turn to "start", and engine starts normally. Very disconcerting.
I think I'll try replacing ignition switch myself first, to see if it resolves above issue, before taking it to my Indie. I wont be able to get to it until mid-Jan-2020, but I'll post an update back here when I'm done.

Thank you for your response. In my above post, what I was attempting to convey is that engine died for no apparent reason.
It was like ignition was turned to 'off' without me actually turning the key to 'off'. My assumption at time was that ignition-switch internally was changing from 'on'(ignition circuit energized) to 'off'(ignition circuit de-energized) in error. Once I replaced the ignition switch, these phantom 'engine died / ignition de-energized) events stopped occurring.

I have an issue I'm trying to sort out where I've shorted something and my starter is spinning whenever I have the battery connected to the car, which is why I found this thread as I'm likely going to remove mine to inspect it as well, and probably replace it. The part I've ordered is the 997....07 version
Glad that fixed your issue.

Well I just did the job. My issue is that I’d turn the key and the steering lock would release but 30% of the time nothing more would happen. Wiggle, jiggle, twist the wheel for a while and then the rest of the dash light would come on and it would start. Annoying and hopefully a new switch solves that. The date code on the old one was 2017.
Yes you do have to DISCONNECT THE BATTERY so the key stays locked in the ignition as you get it into position to screw the locking ring on. If the key falls out you almost need to start from scratch (ask me how I know). Not to mention the footwell light burning your hand in the limited space you have if you don’t.
Right I’m off to do the same job on my 996 - part is 1/25th the price and 25x more painful.

Common sense tells me it’s something to do with the shift linkage or something to do with the transmission.
Will take it to my indy soon and will follow up with the diagnosis.
Looks like it’s time to spend some cash.

Having the key stuck issue in my 997.2 also. My son replaced the ignition switch today and it didn’t fix the problem. A fault warning comes up on my center RPM gauge that says “Please put the vehicle in park to remove your key”. Seems like I read where others in this thread had the same message.
