08 honda accord, bypass

does anyone know what key bypass i'm supposed to use for the 08 honda accord? i used the dei 556uw and it turns on and then turns off. i don't know what else the problem might be. anyone with info please help. thanks

Bypasskit lists the PKH34 and 556U among others, so your choice isn't inherently bad. Did you use a valet key or one of the master remote keys inside the 556U?

A valet key should work with no problems. I personally wouldn't use a master key without disassembling it and looking for the transponder...there's a possibility that if you just put it directly the transponder part of it will be so far off from the antenna inside the box that it isn't picking up the signal at all.

Check to verify that you're getting good 12 volts, ground, and ground-when-running.

Check the antenna positioning around the key cylinder as well.

i'm using the valet key. the engine starts and stays on ffrom anywhere of ten seconds to ten minutes. can't never really tell. when it cuts off i hear the 556uw click. i replaced with new one and same issue. i will use pkh34. thanks.

I'm pretty sure PKH34 doesn't work on the newest Hondas. They said it did, wasted a lot of our time, and we had to take them out.

Does their site still list the PKH34? I thought you could only use an XK05 now.

Anyway, ramon2001,

If the car starts at all, it's not the bypass. Once the remote start starts the car and it's running, you could unplug your bypass module, and it wouldn't make any difference.

What kind of remote starter are you using?

Are you using tachometer or voltage sensing?

Agreed with Chris Luongo - and I should have thought of it in the first place that a Honda would crank but not start if it didn't see a correct key signal when the ignition powered on.

Definitely a tach or voltage sensing issue.

Also, if Chris would elaborate on what problems the PKH34 had? Didn't think the PKH4 firmware on the XK05 would be different.

we use the pkh34 on all the new hondas and it works fine

the carbine start2-plus was installed and i did notice that there isn't anything tapped into the injector wire for the tach. i have never used carbine and i dont have an install guide.don't know which one is the tach wire coming out of the alarm. if you know, will you please let me know which one is the wire color. thank you.

it may not go to an injector but the tach test plug or any other point in the vehicle.... i had a few Hondas and Acuras that were very finnicky... the RMP would ramp up or down  while running and the R/S would shut down sensing an over/under rev.... usually i program these then for voltage sense....

as already mentioned if it starts fine and runs more than 2-3 seconds it is not a bypass issue......

where can i find the tach test plug? it's an 08 honda accord. the wiring diagram indicates to get from a coil or injector. don't know what to do?
