Glad to hear you got it started. What year's your car, miles and what part of country do you live in? Not in favor of throwing parts, but you might want to consider replacing ignition switch if this problem reappears. Here's a video for replacement on a 996 - different model I know but steps should be similar.

I prolly spoke too soon. Here's the ignition switch from FCP Euro, which is different from the inexpensive part in the 996 video. Note it doesn't come with keys, so that'd be extra expense at the dealership, plus it may require PIWIS pairing.

Best bet is the ignition switch. It's a common issue with .1s but not sure if the .2 uses the same part. It was the first thing I replaced on my car. It happened once during my test drive but I couldn't replicate it and the prior owner just thought I was an idiot. Symptoms included a slight delay between when I turned the key and the starter would engage. 1 in 10 starts nothing wouldn't happen at all. It would typically work if I took the key out and tried a couple more times.
My indy replaced for $250. Its a very easy DIY I believe. The switch costs maybe $150.

The 997.2 uses a different part - see the link to FCP Euro in my post #17. It's ~$190, but more bad news is that keys to fit it are not included. When that's figured out I'm guessing it's got to paired via PIWIS. Potential here for large cost methinks.

Just checked and looks like it uses the same part.
997.1 Ignition Switch - Porsche (997-618-159-07) $186.75
997.2 Ignition Switch - Porsche (997-618-159-07) $186.75
Doest looks like it needs to be reprogramed. 30 min job. Bruce in Philly wrote a DIY on it here: https://rennlist.com/forums/997-foru...placement.html

Hey man, I recognize you from e90 M3 forum. Small world !
No updates yet. Car starts every single time now. I don't know how to troubleshoot this problem if it is intermittent. Does anyone know if dealer or indy would figure out the problem?
I don't want to start replacing parts just for a guess. That never ended up good with me and my wallet gets tired quickly
I do hope I don't get stranded again. Everytime I try to start the car, I pray it turns on.
Also ignition switch on 997.2 are not common problem as it is 997.1 When I turn the key I hear click every single time so it means ignition switch is working just fine (even at time when I couldn't turn it on "I believe" but I have to replicate it again to verify)
Does anyone know what are the signs of ground problem? Does interior lights work fine and dash console if there is ground problem?

- I have had the same intermittent issue, although it became a real problem yesterday. It first was noticed 6-8 months ago. [MY 2012 997.2 Turbo S]
- In the past, I’d simply remove/reinsert the key, and it’ll start. The Key FOB battery is ‘current’ [changed 3 months ago]
- Yesterday, it took 8+ times & twice I received a message indicating I needed to ‘Apply The Brake’, which was already ‘applied’
- Battery is the Porsche OEM “AGM” 80 Ah & was replaced/installed 15-18 months ago
- The Porsche ‘Trickle Charger’ through the cigarette lighter is connected if I’m not driving the car for more than 2-3 days, so it’s not the battery
- I’ve started carrying the 2nd set of Keys as a backup, but not yet used them. And I’m not convinced it’s the issue anyway
If anyone has experienced this, or has a solution, I’d appreciate the information being shared. [Maybe it’s the Key Switch ...... Pure Guess! But, I’d hate to have this occur on the road!]

Hi 'Swingwing':
- Thanks for your thoughts. [And, I think you're correct!] It's a 2012 997.2 Turbo S. No prior issues & owned since new.
- The problem [see above] hasn't been a real issue until yesterday. I could always 'solve' the problem by removing/reinserting the key. Not so yesterday.
- Car wouldn't start - but did after multiple attempts of inserting/removing/inserting the key. [That's how I've always solved it in the past.]
- With the engine running [after dropping off a passenger 10+ miles later], I could not move the shift lever out of Park. Never had that occur.
- Didn't want to shut off the engine for fear that the potential 'Key' issue would 're-appear', so I kept re-applying the Foot Brake, and attemping to move the shift lever.
- On the 3rd or 4th attempt, I was finally able to move the shift lever out of Park. Later, upon re-start [45 minutes later], everything worked OK
- Initially, I was thinking it was the Ignition Switch cylinder [which multiple individuals have reported], but now I'm wondering if it may be the foot brake sensor.
- Candidly, I didn't know it was a 'Known Issue'. I've always assumed it was a worn Ignition Switch cylinder, which I've 'lived with' but not replaced. [Will now!]
- Still, If you can refer me to a 'YouTube' video on correcting the potential misaligned foot brake interlock switch, it would be appreciated.
Thanks again, for your insight!
