I understand that for the older stuff, their is a keyset you can get from a
dealer for about 200 bucks, which includes all new keys and locks for all doors, windows, ignition, etc., Is this true? if you have done this , were you satisfied
that the locks are now more break-in proof?

 

I've never heard that.
I have heard that up to a certain aged vehicle, you can take your VIN and proof of ownership to the dealer and have new keys cut to operate your locks. But I've never heard of getting new locks that are more 'theft-resistant' than the standard ones from the vehicle.

200 bucks sounds about like the cost one would incur changing all the cylinders to a new key though.

 

yeah, from what I understand, the foreign cars that came from asia; honda, Isuzu, toyota, mazda, etc., from the 60's, through the 80's, all used a softer steel in the locks; they did not use hardened steel, or steel/alloys on the locks.
so the soft metal, after thousands of turning keys in them, pretty much ate up, any and all corners that once obstructed teeth cut into keys. so that almost any old key, from one of these mfgrs, would turn another keylock, from a whole different car. I thought somewhere I had heard or read, that toyota sells a keylock replacement set, for their old stuff. I am hoping this is true, since my neighborhood, has a lot of , shall we say, not for sure citizens, who look for certain vehicles to strip down or sell, back across the border.

 

if you have a real concern, you can go to a total remote keyless entry, even if you didn't have electric keylocks to begin with. even those could be broken in to though. so otherwise, short of having the 'smartchip' in the key that keeps the car/truck from starting, any lock cylinder can be picked.
well except for some of the rare dual/dual-pattern keys I've seen, where instead of just grinding off the edge (top and/or bottom) of the key, there are also 'dimples' ground into the side of the key so that it has to move a keyway either 'up' or 'down' and to the 'left' or 'right'.
