Tight ignition when cild

[DenverSteve]

Well, I don't consider the west coast (los angeles area) cold. So, I would check with another mechanic. My car, even in the garage, is regularly in 30 degree weather and I've never felt any tightness even in my vehicles parked outside in the snow (not a Porsche). Whether it is or not, it sounds dirty.

That's after 4 Porsches and 2 Boxsters.

It was 40F on my way to work this morning which seemed "cold" to me. And my mechanic works for ALMS and GrandAM teams during the racing season so I tend to trust him. I'll let you know what I find tomorrow.

I'm not suggesting your mechanic is incompetent or even wrong but; A) most mechanics don't worry or care about ignition switches and; B) these cars are driven everywhere COLD exists without issue. It's easy for a convertible car, driven topless a lot, to have grit, dust and debris in cracks, crevices and even ignition switches which can cause tight, squeaky or sticky issues that closed cockpit cars don't readily see.

Additionally, cold causes parts to shrink not expand which could make it loose or rattle before it "tightens" up. If it's problematic, you could take it out and clean it or replace it. I've never had a problem with one of mine but I have heard they can go out.

it is true that the reason for the ignition switch not to turn on is not the cold weather. its because the switch is defected and need to be replace.
the cold weather just makes it worst.
in my car, the switch works fine most of the time, but on a cold morning (and i live in Florida) it will give me problems.
the question is, if one decide to replace the ignition switch, how can the keys of all looks in the vehicle can be matched?
(assuming the new ignition switch is coming with new key blades)

Thanks for the replies. At least I know others have seen the same. I have a spare inanition switch, the replacement version. It doesn't seem that new keys are necessary, correct me if i'm wrong.

Buy yourself a spray can of "fluid film" and spray into the key slot (with force !!) . This will help a whole lot !!!. Also use "fluid film" on all locks, switches, battery cables and top slides , cables and linkages. This is not grease. It is "Lanolin" base lube and protector. GREAT STUFF, been using for 25 years.

Take the switch apart as described in Bentley. One paper clip and the correct maneuvers then lubricate the parts once its apart. Did this for several years, worked perfect no new switch needed.
