Jeep key not working

[Hound]

I have an 08 Jk and it only came with one key. I did have a second 'dumb' one mad, that while it wont start the Jeep it will let me in if I get locked out. Standard $5 cost for it to be made. When I called to have second one made the $200+ cost seemed a bit steep for a damn key.

Ace hardware has a sign that says that they make keys with transisters.

ACE wants 2x as much as the local lock smith that came over and reprogrammed our keys, for $50.

Call AAA if you're a member or do a search online for a locksmith .

Happened on my wife's Nitro. Unhook the batter for a little bit and it might reset. Worked on her car.

Hahaha that worked. Started right up. Will go get two more keys Monday. Thank you

Could be worse. Newer Porsche keys are upwards of 600 bucks.

I tred ACE a while back they need two keys to do it

They were able to clone mine with just one key. On my grand cherokee, if you have both keys, the car will program the new key for you

Try locking, unlocking, then relocking the passenger side door (with the physical key, not electronically).
I know, it sounds crazy and probably won't do anything, but try it.

Just an FYI. The positive battery cable on many cars / trucks. The small red wire coming off the battery control's everything but the starter. And corrosion can and will build up at the battery in the wire. Preventing any start-up. I'd check that before buying any more keys. The moving of the cable might have loosened any corrosion making contact and there fore starting the vehicle. Happened to me on 4 different vehicles.

Depending on the type of "chipped" key, you might be able to solder in a resistor on the "sensor" wire under your dash.............I don't know the jeep for sure but I know some gm cars can be bypassed this way.

That's the early pass key 1 system. We used to do that at the dealer. The new systems after like 96 normally use a rolling code system and I don't think it works.

Ah, good to know. I just remembered the trick from a prior job, didn't know if it would work on this application for sure or not.

I had ACE do my 2007 Wrangler with only one key. it worked fine. we just double checked it would start the jeep before I paid for it. all good there.
