Re: Alarm lock cylinder

Hello Mathew. Try Jeff Salz for your key needs. He does some, however, I'm not sure if he does what you have or not. Jeff is a member here so yo can find his contact info in the Membership section/tab.

Hope this helps!

Re: Alarm lock cylinder

Thanks for the referral. I can't help with the B&S keys used for early alarm locks. Best to just buy a new one since there is no correlation of the alarm key and glove box/spare tire lock as in 71 up cars.

Re: Alarm lock cylinder

My car uses the later switch cylinder like the 1971, so same key as the rear compartment door and spare tire.

I am am not sure the differences between my original cylinder and the later mid 70s one (like this one https://www.paragoncorvette.com/p-35...ey-switch.aspx)

Re: Alarm lock cylinder

The rear key switch for my alarm system is problematic. Is there a source or process for repair or replacement of the cylinder? My 70 is in the 15k range so the B&S cylinder isn’t correct.

I understand the mid 70s version is available, but not sure the differences between the two. Is there a way to rekey the lock to match my current keys?

Mathew,
Sorry, I misunderstood. You can purchase a replacement lock and have your glove box/spare tire lock re-keyed to the new alarm lock. Then the new key number can be stamped on a new correct key. The key that comes with the new lock will be a Stratec key without knock outs. I don't believe that the alarm lock can be opened to be re-keyed but I know that the others can easily be re-keyed. You need to be sure that the new lock has a "K" rail code (for 1970). Others may know a way to open the alarm lock and I would love to know if I am wrong about this and if it is possible.

If your 1970 is later than about s/n 12,250 it will have the alarm lock shown in your Paragon link (See TIM&JG 6th Edition Page 55 ). Your challenge will be to get it keyed to match the interior storage compartment and spare tire lock. Any number of NCRS members can do that task for you. -- Peter Lindall, Jeff Salz, or Gary Beaupre.

Re: Alarm lock cylinder

Wasn’t sure the the replacement switch was different in configuration.

To be honest, I am not either. I was referring g t the difference between the earlier Briggs & Stratton lock.

How much different can the outside of the lock be? There isn't much sticking out. I doubt the Exterior judges will be able to see enough of the back-side of the lock t0o tell if there are any differences. Now that I have said that they will go on a hunt for those differences.

Re: Alarm lock cylinder

The configuration of the later 70 up alarm switch is quite different from the 68-E70 switch. Attached is an early switch. The later switch is flat and appears more like a door lock. Hope this helps.

Re: Alarm lock cylinder

I assume switch does not work electrically. I do not think the switch can be disassembled and cleaned. On my 74' the switch would not work electrically. I removed it and submerged the entire switch in a glass with a mixture of two parts white ammonia and one part hydrogen peroxide and left it for about 20 minutes or so. I rinsed it off with water and blew it out as best I could with compressed air. The switch was checked with a VOM and was ok so I reinstalled on the car and the alarm system was working again. You probably have these two chemicals at home. Mix some up and put and old brass bolt or nut in the solution and watch it work. That is what I did first and was amazed at the result. Hope this helps and if it works for you let us know.

Jeff,

Perhaps I misunderstood Jeff, but I understood he was asking if the Paragon switch he linked to had a different configuration than the later switch. It is my understanding his 1970 is a later production model.

The configuration difference between the early switch and the later switch is obvious, as you have pointed out.

Perhaps we need to hear clearly from Jeff as to which switch he is referring to.

terry,
Perhaps it was me that misunderstood. The Paragon catalog I have does not list a 68-early 70 switch. I ASSumed that Mathew was questioning the difference between the 68-E70 one and the one shown in the catalog.

We will need to hear from Jeff to clarify. I remember talking to him about his 1970, but I can't recall the serial number or even the approximate time frame.

In the mean time I think between both of us, we have laid out the alarm switch situation for chrome bumper C3s.
