The battery in my keys transponder had been getting weaker and weaker until it died on me last night. Got locked out of car at midnight at a walmart and had to get car towed.

I went to my local honda dealership today at lunch and told them I needed a new battery. I asked if I needed to have my car present and if I had to get the transponder reprogrammed? I got a no and a no.

I get home after work and my car won't start. I opened car no problem so I know the new battery is working fine, but when I turn the key, it doesn't even crank. Well, maybe for less than a sec and then nothing.

Car battery is fine, and I have never had any problems with my 2004 accord 4 dr lx.

Anyone have any ideas?

Thanks in advance.

That's in the past. But, you didn't need to have your car towed. 1. Can't you open the car with your key? 2. The passive alarm will kick in. 3. Start the car (because it's the right key). 4. Drive. It will look like you stole the car, but it will drive. I've done this before on my 06 EX. 04=06.

How do you know that your car battery is still good? Did you use a volt meter? Is the eye still green? Both may mean nothing if the CCA is low.

sounds like a dead battery or an evil cable end. I just replaced a battery cable the other day for no start on a 03-07 accord. How do you know the battery is good? To jump to a faulty key is premature seeing the car will not even turn over. Essentially a few things are needed for a car to turn over-- good battery, power wire to starter, ground path from starter, and a starter signal. Which one of these are you without?

I don't think a dead keyless entry is going to prevent you from not starting the vehicle. The immobilizer chip in the key is completely seperate from the keyless.
