Default Dead Battery in Key

Kinda a repost from another issue of my "PT DIED" I only have one key for the PT. I changed the Ign switch and acutator but not the key cylinder. If the key "battery" is bad will it not crank the motor. All I get is lights turn on but no crank. Trying to determine if it is the PCM or I need to replace the key cylinder as it may not comunicate with the car if the (key battery) is dead?

Thx for your help

If the car doesn't recognize the key it will still start but die within a few seconds.

If it's the key with the grey end on it, there's no battery inside, just a chip.

If your key has a battery, it is for the remote keyless has nothing to do with starting and ignition. A transponder key, like the one in the pic posted by Crewzin, has no battery. It has a non-volitile memory so it doesn't need a constant keep-alive voltage. It is powered by the electromagnetic field generated by the coil around the ignition lock.

As the others have said your key is fine. You may have a bad starter or some bad connections on they cables. Clean they big ground on the inner finder as well all the other cable ends.

If you have a post 2006 model with keyless entry, then you have a battery inside your key, but as stated already, it doesn't affect starting.

You may very well have a bad PCM, which is very common, but it is not related to your key, and there's no reason to replace the tumbler (key cylinder).
