2003 honda accord alarm problem

I am assuming that this is a four cylinder automatic--- There is a neutral safety switch on your automatic shifter- Make sure that your shifter is all the way into park , You can unlock your shifter with your key or some like object, take it to neutral and then back to park!
2. check your starter connection to the battery, if loose or corroded clean and tighten. I don't know what level of mechanical you are but at this point take a screwdriver and cross the posts, it will spark so don't freak out. If your connection is good it should turn the engine if it does not engage or at least try then it could be a starter solenoid or if it clicks could be a starter. Now if you do this with the key on, the car might start, again don't freak out!!
3. Now there are also fuses in the starting system check you fuses
4. The worst case scenario would be a locked-up engine. Have you or do you know if the timing belt has been changed? If it broke, it could have taken out the top end of the engine ( valves, rods , cam , possible even the rods! like I said this is the worse case scenario! Hope this helps

lube it?

is your battery dead the shifter cant move until you push down the brake.

Make sure that the Shifter is in neutral or park. If that doesn't help, check the fuse and relay indicated for you started in the fues panel.

its not supposed to come out of park without the key , thats a safety feature on all Hondas

for the pannel ,check the fuse ,for the shifter you have to unlock it,but it wont move no where with the car off,your car owner manual will explain everything about.step by step.

Sounds like your brake interlock is not working. You can manually override it. Check your owners manual, but there should be a small square around the trim around the shifter. Pry up the square and there is a release mechanism to manually release the solenoid. It should be covered in your owners manual how to override it.
I think to replace it you need to take apart the shifter trim.

Replace the brake switch. It us behind the arm of the brake pedal under the dash. $20 part and 15 minutes to replace yourself.

It sounds like the lever from the gear shifter has come loose. I would first look at the shifter from under the car. You can also remove the boot (or console) from inside the car and check the linlage. Most linkage is held on by a small clip or cotter pin and somethime they don't stay in place anad the linkage slides off the arm..

Does shifter move if it doesn't it could mean a broken shift cable or broken shifter. If both are Good then you have a BAD transmission. These vehicles are known to break shifter cable. CHECK THIS FIRST> Good-Luck and thanks for using FIX YA
