72E door lock dilemma ….

[MT]

Another thing I really should have checked more carefully……

Surprisingly today for the first time I took my 72E to somewhere I felt the need to lock the car doors. It has other security disablers that I always use.

I made the rash and erroneous assumption that the keys that came with the car would lock the doors …. and they don't. Likely that either the door handles or (more likely) the ignition switch has been replaced at some point, and being a race car the need to lock the doors was secondary at best.

So I'm in need of a solution. I know on swb cars the key/lock number is scribed on the rear of the lock mechanism, but I think I read somewhere that later cars don't have any number on them. Potential solutions I guess are

1. attempt to replace the tumblers in the existing lock barrels so that the current ignition key will work (anyone done this and left a record of how??)
2. get a new or s/h set of lock barrels with keys (any known sources? Do Porsche still make these?)
3. get some replacement chrome handles with keys.(the current ones have lots of 'patina' so a shiny new/better/rechromed set might be worth the cost)

They are the proper 'trigger' type for 72MY cars.

Views? Options? Any bits in your store that could work?

All solutions require the door panels/pockets to come off again alas.

Did I REALLY not check this? I must have done…. surely.

The key and lock numbers are on your build sheet if you have a copy of it. This may not help of course but if you wanted to get keys and tumblers to the original code I presume you could with this information.

Not sure what you mean by the build sheet Mike - and therefore likely I don't have one!

Documentation on the car is sparse in its early years - also as I said it's likely the ignition switch is not original.

Example of a build sheet includes key and lock codes.

Why would you expect anyone to have a copy of the build sheet?

Porsche will supply you with a set of locks and keys for about £60 each side.

Its easy to replace the tumblers in the door locks to match the ignition key. I bought a kit from locksnkeys.co.uk ref A-26-101.
The process is described in the 101 Projects book.

I thought, in the interests of learning about our cars (rather than yet another value thread or picture thread) that it would be a snippet that would stimulate an 'oh I never knew that' comment or two.
I have obtained a copy of the build sheet for each early 911 I've had. They make interesting reading.

I concede that I have now found out that you can buy locks and keys new from Porsche from your valuable reply so thanks for that info. which I never knew.

If you don't have the book - http://www.pelicanparts.com/techarticle ... -Rekey.htm is the same article as the 101 Project book.

Only fault I see in the article is by my count 5 tumblers with 5 combinations per tumbler gives 3125 options rather than 625.

Thanks all.

I have the 101 projects book, and have found project 76. I have read that book several times, but never paid much attention to that one clearly.

I also have looked at the locksnkeys website, so reloading the barrel to fit the current key looks like a fun project as long as I can dismantle the existing handles without damage. Might get the handles rechromed while they're in bits.

I know the build sheet as the Kardex, Mike and although I did get one for the swb I didn't for this car…… and now I've cancelled my PCGB after that ridiculous 'handbags' meeting they had a year or so back, getting one will be tricky I suppose.

If the barrels are knackered then off to Porsche for new ones unless a good s/h pair appear.

No one got any shiny rechromed trigger handles they want to get rid of?

Thanks again

If it helps, send me your door locks and the key and I will re key the lock for you. We can re chrome then whilst here (if that helps).

Thanks Alan, but I'll give it a go myself first - then call you if I get stuck!

I know "£10 to fix it, £20 if you've tried first "……..

If you need different lock cylinder plates, they are available here. There are four different versions:

Hi try the key in the glove box lock it's not often that gets changed if it fits you may be able to change the tumblers.

[Ayli Carper]

If you end up at the door of buying new barrels I have a pair of unused ones sitting in a box in my garage you could have for half the normal price.

[RENNSPORT CLASSICS]

Take the barrel out of the handle with the key inserted.

You will see the brass keys protruding. These are the ones in the wrong place. Make a note of relative heights of brass keys.

Carefully remove the key holding the brass keys in with thumb and forefinger.

Slowly remove thumb and forefinger letting springs extend brass keys naturally (let go and they fly everywhere).

Now look at key and compare with notes taken at start and reinsert brass keys in likely better positions. By trial and error you will match brass keys with key so all stay down when key is inserted, Then the barrel will turn (no brass keys sticking up).

The brass keys are of different lengths. Logically match the shortest brass key with the highest point of the key itself.

Or order new barrels and keys from Porsche quoting your chassis number.

It is very unlikely the ignition switch has been changed. Most probably doors and handles on a race car.

PS. Use grease or vaseline it keeps the brass keys from springing out too quickly.

Hope it helps.
