Re-key ignition tumbler?

[kupcar]

Hi guys, I have a situation were a mechanic lost my key and switched out the original ignition tumbler with a new one. The problem now is my locks in my doors, hatch, and gas cap are not keyed to match the ignition. Crazy thing is I had three original keys as spares. Having two keys (one for ignition, one for doors) is a pain. Has anyone re-keyed their ignition tumbler to match their door locks? Do I have to keep the ignition key and re-key the doors, hatch and gas cap. What pain in the ass. I could have dropped a spare key to this guy and not have to deal with this. Thanks for any help, Jeff

Not trying to be a prick here, but if they lost it they should pay to have it re-keyed. I have done the gas cap, it is not difficult if you can get cap apart.

Joe- I agree. It turns out that the original key was not lost. I have an ignition cut-off that needs to be over-run in order to start the car. The mechanic was made aware of this before work was done on the car. Well he must of forgot and thought he was having ignition problems when the car would not start. Replaced the ignition with a new cylinder and key and tossed my old. Did not charge me for his effort but now I have three original keys that open the doors, hatch, gas cap and glovebox and one new key for the ignition. Nice!!!!

Hey Kupcar, Man, it sounds like the guy who changed out your ignition switch wasn’t thinking too clearly. I don’t suppose he would have the original part laying around somewhere. One of my buddies has every old part he has ever removed hanging on his garage wall. He likes to point at some obscure object and tell you about when he changed out the muffler bearing on a 917 long tail Porsche.

Re-keying the 928 ignition and door tumblers can be a pain. Luckily when I needed a couple of duplicate (long shank) spare keys - I was able to send my original out to California. None of the local lock smiths would even attempt the job. If I remember correctly, I coordinated my project with 928 International. Perhaps they will be able to recommend someone to help with re-keying your ignition switch.

Good Luck, Michael

Michael, I wish he would have saved my old tumbler, but no such luck. It seems to me if the ignition can be worked to fit the original key then that would be the way to go. I still have three original keys. One tumbler change compared to four. Don't know if it can be done. Jeff

[Mrmerlin]

you can take the ignition switch out and move the tumblers around to fit your old key,
if you dont want to mess with taking it all apart 928INTL,
may be able to make it work with your old key or send them one of your old keys and they can make a used ig switch match your key

[kupcar]

Mrmerlin- Thanks for the input. I'll have to give them a call. Jeff

[Landseer]

Yes, I've done it several times and have pictures.
Its not hard to do.

928 Intl option is also a good one if you don't want to mess with it.

[kupcar]

Am I going to need additional cylinder pins? Never took one apart. Jeff

[Landseer]

Probably a few. There are 5 different pin numbers.

There are a few good threads with pictures, including some of mine, on rennlist in the 928 technical forum.

Just search "ignition lock" in the 928 forum.

Here's some examples with some overall pictures.

I agree with Landseer, I did this to my Gas Cap. You take the tumbler out and put your old key in it and file down the pins. There's a write up with pics somewhere. Very easy to do yourself.

[kupcar]

Thanks for the info. Looks to be pretty straight forward. Can't wait to have all the locks working with one key!!!! Thanks Again, Jeff

[Landseer]

The shop that did it might have the spare tumblers.

I don't file them, usually find the right ones instead.

I do lay them flat on a sheet of 600 paper to polish them a bit to remove the edge that develops where the key drags across them. Also, use a silicon dielectric grease on reassembly -- great lubricant for this work (used sparingly).

Biggest issue / only issue I've faced is removing the pins that hold a lock together usually 1 or 2. Hard to drill them without wandering into the aluminum. Usually I end-up making a bigger hole and threading/ loctiting a tiny allen head screw in place of pins on reassembly.

[kupcar]

Landseer- Thanks, It's great to get all the fine details on the project. I will polish with 600 grit and a bit of dielectric grease. I can't wait to see what kind of pin they used when they replaced the original tumbler. Hope they didn't create a bigger job. Jeff

[Landseer]

There is supposed to be a retaining pin on the top of the steering wheel support casting that holds the entire lock in the casting, and I think one pin that holds the tumbler cylinder into the lock body that will become evident.

[kupcar]

Well I hope it comes out easy! Jeff

I have a key problem. I acquired a 1984 928S..... NO KEY(s). Doors are open, rear glass is closed, glove box locked. Ignition is locked.
How many keys are required for the 1984 928S; One for ALL or ignition separate from others?
Is the ignition key double cut in 1984 OR is is similar to a 1986 944 type?
Will factory supply new key(s) w/ vin number and proof of ownership?
Can I remove the 928S cylinder and replace it w/ 944 cyl.?
With battery power or manually, I believe I can open the rear glass to access the cylinder; maybe replace it with a 944 part. Same with the door locks(???). Glove box might be more difficult.

WallStreet, No a 944 part will not work for any of the 928 locks. 944 electronics are more Audi and VW supplied parts. The 928 is all Porsche. I have a spare 928 tumbler and 3 keys, but I really don't want to get rid of it. The tumbler can be pulled just like in the photo above and behind it is the steering lock. It can be pulled out to steer the car for easy movement. I believe they explained above that your tumbler can be matched to an old key by 928intl. It's not cheap, but talk to Tom if you call. Otherwise you can be cheap and just buy a new ignition tumbler with a key from one of us and lock yourself out of the car by accident on any given day (because any old key won't unlock your doors or trunk). It's hard to get Porsche to do anything with rekeys. My advice to you is look very well inside and under the rear of your car. Sometimes a key will be hidden somewhere. I found one taped under the rear of my '84. I believe these guys are explaining how to roll your own tumbler with an old key above. This is for the skilled techy that isn't afraid to break things.
And Kupcar, that mechanic would be buying that $100 plus tumbler from 928intl.com so you know it's done right. He did it, make him fix the problem.

If the locks are original Porsche can make a set of keys from the VIN, mechanics do it all the time when keys get lost etc. Its about $60 and you will need to do it through a dealership.

Normally a single key does all the locks except gas cap, but locks get messed with so they may not be what they used to be.

[wallstreet]

A dealer parts desk told me: Porsche can supply key for about $100 plus vin number and copy of title/maybe proof of ownership papers. That would solve the key problem as the new key would fit ignition, doors and glove box.
OR I remove the cylinder and have a key made to match cyl.
OR purchase new cyl w/ key but doors etc will not match.
Is the key similar to a 944 key OR is it "internally" double cut making it a key similar to a Volvo key?
