SOURCE: When I turn the ignition key the van won't start.

Is it a single click? If it is, check your battery cables and be sure they are clean and secure. A loose connection can cause this problem.

My van wont start i don't know if its the starter


a common problem is the ignition switch (electrical) and must be reprogramed by the dealer. If u know how to use a test light u can check it at the starter relay under the hood. Of course the battery nust be good and u could have a bad key.

Change starter on 2002 tahoe now motor wont start


If you had battery unhooked and assuming that it is turning over try this Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. If that dont work try a different key do the same thing. This relearns your key to the ignition it started with Gm cars and trucks from 1999 to to 2006. It is a big problem but there is no recall that I know of. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

Reprogramming blank key iveco daily


Unfortunately there is no solution to this except to take it back to Iveco for reprogramming.

I am led to believe from my locksmith that there are two types of transponders generally put into cars and vans.

The first is a simple chip wtih a code which matches a code in the car / Van

The second is a chip which has a set of codes. They are read in order and the car / van remembers which one was used last. If you use the wrong code in the sequence then the car / van will ignore it and not let you start the engine.

The Iveco is unfortunately in the second group. If, like me, you snap your key, you can superglue a new key to the old and it works fine. The chip doesn't need to be "too" close to the barrel. Yes, it looks ugly, but it's much cheaper!

Reprogramming a spare with only 1 original - 2004 Chevy Malibu


the ignition keys are not coded. no "chip" in them you should be able to just have a spare key cut and it will work fine. These use an electronic device in key cylinder that senses the proper rotation of cylinder and tumblers. so if someone tries to pry on with a screwdriver it will disable starter. when this is replaced it has to be reprogrammed
