Ignition key switch fried?

you may change the complete ingnition switch with key and remove the door locks and rebuilt them to this new key or just put in an extra starter knob you may start the engine with

 

hello daniel,

this I never heard that the yearly or 2 yearly road inspection will nor accept this starter button. here in germany we never have problems with this when this button is switched so that it works only when the ignition is on. but this is no problem to make. I also have registered some cars in france and there the controle technique accept this starter button without any problem or discussion.

it shoud be all equal in whole europe with those regulations??? you may ask about this there

to change the inside of the locks I did it already on some VW, BMW, MERCEDES, FIAT and also on Ferrari ( 365 GT 4 - 2+2 and also the 400 ) I think it would be the same, but not sure. it takes normaly about 30 minutes each lock when I only have this lock and the key and the right plates to change. otherwise those plates have to been adjusted. on a TR I never did it until now and I also don´t know how such a TR lock looks like because never had one to fix. you may put one lock out and make a picture, then I can tell you if it would be easy or not.

the question is if it is worth the whole labor because of having then only 1 key for all???


on my TR 87 I just have the dashboard out because of installing a touchscreen for all my meassurments. as I see there the ignition switch and the electrical part is one piece? the whole part is fasten by 2 special srews what will brake the head when they are fixed right. so to remove this part you have to destroy those screws. may be that the electrical part is separatly and could be removed on a simple way? and could replaced then by a FIAT part or any other italian part. most are very equal.

I would first remove the keyswitch and habe a look what is really wrong. may be you still can fix it? good luck !

 

Off-Topic, sorry: you wrote "on my TR 87 I just have the dashboard out because of installing a touchscreen for all my meassurments "

Can you make a new thread about it with text and photo's please ?

Hi Daniel, I remember you were over here in Holland and had a starting problem also ...

We rumbled at the powerlead and it was fixed then ......

Why should the starter be burnt ? How do they know that ?

 

Some ignition barrels are separate from electronic switch, and simply clips on to base of barrel and turns with keys to different terminals on, but the year of car it probably has the sealed unit to prevent it popped off to start with screwdriver by thieves.

Anyway it all comes apart with patience and knowledge, as it wasn't fabricated in one piece with different tumblers, and the electronic switch at the base. The problem is the barrel will not come out without removing it from the column. And the column is held together via sheer bolts where the head of the bolt snaps off to prevent removal by a thief, so a drill is the only option.

A new bolt should be supplied with barrel, but when you have a ignition barrel (either new or old ) in your hand with the key in the ignition half way down the stem there will be a a small hole the size of a matchstick.

Now you put the key in the ignition and turn to position 1 and push something in the hole (might find it easier to put something like Allen key in hole and keep it pushed in whilst you turn key and feel it push in pin) then pull out the barrel with the key ( don't remove the key as the tumblers can fall out and give you problems).

Repeat with other barrel and put your old key and barrel in new barrel with new switch, make sure the switch has not turned ( so barrel pin will line up with switch ) push in until it clips in place turn key to check it all, remove key and put it back in and turn to make sure it all works.

Now put it all back together, and you have new ignition with old key, if you are not capable of doing it yourself depending on time involved in removing sheer bolt ( snapped head bolt), but I would imagine any decent mechanic will do this in less than 2 hours. And the process of barrel swapping will take less than 5 mins, so it's worth asking if you are having the barrel replaced anyway.

Hope this helps.

 

so not such a big deal as you thaught first. good to know this with the plates, so same as the 365, 400 and 412, and I think much more other also
