Can you spray something on your key or in the ignition to make it recognize the key

Posted by on

1 Answer

How would that work?
You don't spray anything into any vehicle lock
or electrical part.
The key has to be programmed
That is in most owners manuals
Some vehicles need 2 programmed keys,
just for it to start

After replacing a dead battery .It started and ran for a couple seconds the quit and now it trys to start but won't.I've checked all the fuses pertaining to the engine and Gas the are all ok

It may be that your key or immobiliser system don't recognize each other since changing the battery.

Try putting the key in the ignition and turning it on - leave it on for 30 seconds and switch off, and repeat the process a few times. Whilst in the car with the ignition on, try locking and unlocking the car using the fob/remote. Then try to start the engine.

You say you have plenty of gas - but is it getting to the engine? Can you hear the fuel pump briefly kick in when you turn the ignition to on?

Test the fuel pump. If you can, disconnect the fuel line where it enters the engine bay and turn the ignition on. Fuel should literally spray out at pressure. Though having said that, if the car was running okay before you changed the battery, it's probably not a faulty fuel pump.

If still no go, get somebody with on OBCD - a scanner - to check for error codes just to rule out something like a faulty crankshaft sensor.

Ignition stuck on lock

1. Check battery - even if otherwise good, if it measures under 12 volts (even just under) it won't start. Saab's are finicky about that.

2. Does immobiliser recognize the key? If not, it won't turn. Are you using an original key mated to the car or a replacement key fob without the electronic guts?

3. Does key open the door? If so, put in ignition, turn to ON (if you can) and press Open Door button on key. Try even in Off position if not.

4. DO NOT spray anything into the ignition keyhole (as others may suggest). It will gum it up. If you have to, remove ignition keyhole and clean with alcohol.

I own a 95 mercury cougar and I can't get it to turn off. It will start just fine but when I go to turn it off its like its not hitting the switch to shut off. I'm not sure what to do. Help please

sounds like someone spilled something arround the ignition switck or something like that,try spraying the switch with WD40 or some type of spray lube.
try to use something that has one of those little red straw type extensions that fit in the sprat nozzle.
that way you can direct the spray to locations that have friction or movement.
if that dosent work the key ignition switch will now have to be remove and inspected or cleaned.
At worse the switch will have to be replaced.
good luck,Gary

My engine was started i realized i can take the keys out and the car was still running is this normal or something i need checked?

not really a problem yet the key or ignition switch is worn down and allows removal but with the security imbedded in the ignition systems the key may not work anymore or the ignition switch wont turn or recognize the key either use other key or have a new key made if old one is worn down to avoid a key break in switch

Key will not go into the ignition on my VW jetta

There is a security flap that is supposed to recognize only your car key. Sometimes this flap can get stuck down. The quick fix is to have the dealership get some WD-40 sprayed on it so it wont stick. The more permanant fix (and better fix) is to have the dealership replace your ignition. The ignition is covered under most warrantys.

I have a 2000 Ford Focus that the key won't turn. In order to remove the ignition cylinder, the key needs to be turned to the accessory position. If the cylinder is frozen and the key won't turn, how do...

This could take some patience but it will work. Get some glass cleaner in a spray can. Spray liberally into the lock cylinder. Then using a small hammer or something with a little weight apply turing pressure lightly while tapping the key. Remember lightly. Then once its turned you should be able to get the key to turn. Remember to be patient. It could take up to 15 minutes but it will work. Use an aerosol spray cleaner. These work the best. Good luck.

try lightly spraying a little WD-40 in and working the switch a few times, not a bad idea to do the same thing with the door locks every once in a while. Hope this helps.

Ok, a couple of questions: 1. how long have u owned the car?
2. has this ever happened before, but the key came out eventually?
3. Has it ever felt like it was sticking when removing?
Here are a few ideas, When the key is in the off position, are u pushing the key in towards the steering column, while trying to turn it further to the off position (counter clock wise as u face the ignition slot and key)?
Try spraying a lubricant (wd-40 is excellent) around the key, into the ignition switch (u won't harm it)
Wiggle the key around, and spray several times, this just might work.
If all this fails, I'm afraid something came loose inside the switch, (unusual due to the car being an 07 and a Honda) which is preventing removal of the key. Please let me know how u make out Good luck countrycurt0
