Lost our key that turns off horn

Ok well Lord knows I have lost a few keys! Let the horn blow away!

Just kidding locate the horn should be in the front grill or fender well. And unplug it for the trip to the Nisson Dealership they should have a master key and will order you a new key if not in stock. And don't forget to plug it back in when you get the new key. Hope this helps. good luck

Wont start dash lights up perform service

what engine of the many, you cant fix one , unless you know what it is.! (cyl count and displacement works "cc's")
wont start. but cranks fast?????
dash lights up , key on, they all do all cars, its the lamp tests.
perform service, i just can noodle that. what does that mean?

1: check all fuses. in both boxes, EFI needs many fuses to work.
2: if cranks perfectly , does it?
3: we check for spark , in the blind hope compression is good all cyl.
4: spark is good, (and timing in the realm)
5: i then check spark tips, flooded, or dry ?
5a: dry, try test fuel. (spray)
5b; wet, i use supers secret (in opr guide) unflood mode.
"wide open throttle cranking"?
it starts and runs.
it start then stalls and floods again
or it was dry and runs for 3 seconds, test fuel tested.
so you lost injection
if lost, then we check fuel pressure next 30psi min,
cranking, if not 30, we check for 12v at pump, and so on........ask
ask for help if you make it this far.....
takes tools it does.

When starting motor first all gauges respond until theft light comes on then motor shuts off what do i do

Your security is malf or triggering because 1. Car key or computer has lost its programming, 2. You lost your original keys, 3. Passlock security system is faulty... These cars come equipped with Ford's PassLock theft system. This system requires a key with an internal chip in it and must be programmed for the vehicle before it's usable. In some cases even if you are still using the original key, the key or computer may lose programming. If this is the case you must have the key reprogrammed by the dealer.

Lost the key i take knew one the car fail to start

Your previous key may have had a chip in it. If this is the case you will have to go to the dealer. Also check your owners manual if it has the key code for your key.

hi, the problem your having is going to be with the imobiliser the key that you lost was programed to your van so that when you put the key in to start it then this would turn the imobilise off.

Now as you have got a new key you need to take it to your nearest main dealers with your owners documents and ask them to reprogramme the key for you. The problem you might have is unless you bought the key off them they might ask lots of questions so make sure you take id and owners documents with you.

Now if the key you have replaced with isnt one that can programme to turn off the imobiliser then the chances are you will need to purchase the correct key fob off your nearest main dealer.

Let me know how you get on or if you need further assistance ok

Lost the only key I had for vehicle

Is the car locked? If not remove the glove box lock or a door lock and take it to a locksmith to make a key for you.

Program my Honda accord Key

I've not heard of Brake Codes working on the 3rd or 4th generation Rolling Code Sidewinder Keys. There is simply no reason to, since a Honda Tech can simply access the Immobilizer System through the HDS (Honda Diagnostic System Laptop) with the Daily Access Security code providec by the Honda System. He can even reflash (reprogram) the ECM using this Daily Code.

In a case like this, normally Honda will have the Accord towed in and do a "All Keys Lost" reset with a new set of keys. This will also prevent your "Lost keys" from being used in the future by who ever may find them.

If you ever buy a used Honda at a Honda Dealership, most likely they also did a complete Key code reset just in case to protect you.
