Honda accord 98 I put in the car a replacement key without sensor and the car wont start. How do i resset this and use my original key

Usually with a wood ruff key, one side is very slightly thicker than the other. Put the key in the crank channel and see what side fits the tightest. Sometimes you may not even notice a difference. As long as the key fits secure in the channel and the crank pulley goes on without binding.... there should be no problem

you will have to get another key with a sensor it will not crank without the key and Lisa you may have to go back to the dealership to get a replacement key with a sensor in it

Sorry no easy solution to this. and we can't give out that info anyway.

check the wiring on the solenoid on top of your starter.and check your fuses.

There is a sensor under the left hand side of the dash that would not allow it to start, provided that you have replaced the electronic spark module inside the distributor first, which is what it sounds like it would be, When you say you replaced the distributor I assume you replaced it complete!

tumbler's no good. Fixed the same problem on 1999 alero last week.

Turn the key partway on and pull......

either have a shop scan it for trouble codes or buy a scanner your self at local parts store have OBDII scanner and find out for your self it could be a number of things.

make sure you are not using the valet key. if still goes on take the key to a honda dealer and let them reprogramme the key,. most dealers do it for free.

I had the same problem. Turns out the key was worn down. I still had an original "unused" key which I put into the ignition and had no problems with that key. Since this key worked, it confirmed that the other key was bad.

I then had a copy made and put the original key back into my "auto" file folder in case I needed another key in the future.

If you don't have a spare key, you should still have the metal key tag that came with the car. You can take that to a Honda dealership to have a key made from that.
