Lock and Unlock buttons on my 2002 Honda Civic remote don't work?

I press the red unlock and lock buttons and the light flashes on the remote, you hear the car beep, but the doors don't do anything?

Did you just replace the remote's battery or someone just worked on the vehicle? I need the detail information. Does the keyless entry system work before you post this question? Is the Immobilizer system still working? How many remotes do you have for the vehicle right now?

Depends on the situation you will have to do the synchronization or programming for all of the remotes. If the immobilizer is not working then I would suggest you to seek for professional help because the repair requires the use of a scanner, not the "Code reader" that most DIYers have.

The Immobilizer system should arms itself about five seconds after the ignition switch switch off, the immobilizer warning light should flash during this time (Light with a "Key" picture)

So unless I know what the vehicle need then I'll show you what to do. I need more information in order to give you the proper advice and how to procedures. E mail me if you can give me the update information or need more help because I probably won't have the time today to come back to check the question, but my phone will alert if I have e mail. HTH

  • Why does the left front wheel on my 4wheeler lock as soon as i touch the lever but the other 1 don't even hardly slow down? I have a 2007 Honda Recon 250 4wheeler and it's been doing that off and on for awhile now, i thought it might have been a low tire because it's done the exact same thing before with a low tire but my tire pressure is fine. I'm guessing something is wrong with the brake shoes but i'm not sure what to look for because i'm not very experienced in the mechanic department and i don't wanna mess something up worse than it already is Haha very funny Andrew
  • Spare key doesn't work to unlock door electronically? I'm new to cars and my mom allowed me to borrow hers for the next two months while she's out of town. The thing is, she gave me her spare key, and the alarm won't work. The physical key unlocks the car, but I can't unlock/ lock it remotely. Any advice? The model is a Honda CRV

  • My car won't unlock w/ the key remote? - 1 I've a 2000 Honda Civic. Today, the unlock remote wouldn't unlock the car. I replaced the battery in the remote today and it still won't unlock the car. What do I do next, and how would I go about doing it? For example, how can I move my car to a mechanic or dealership if I can't get into it? Tow? Thanks *And how do I get inside the car w/o setting off the alarm? Or is the alarm off now, since the car may be out of sync w/ the remote?
