2002 JEEP DASH LIGHT OF A KEY INSIDE A CIRCLE is on and jeep won't start

It sounds like the vehicle lost its programming or immobiliser settings. When you replace the module, not only does it need to be programmed or "coded" to the vehicle, the security/immobiliser also needs to be "opened". Finally you MUST MUST MUST use the original master key when starting the vehicle after the fix. If you arent using the master key OR if the battery is low, AT ALL, the sync between, vehicle, computer and programming wont take. Any other lights on the dash? any codes? if it is simply the key, try disconnecting the battery (or completely pulling it out to charge it) then putting it all back in and use the master key to start the car. i recommend putting the key to the "on position" for about 15 seconds before starting, crank it up, let it warm up, then drive at a low rate of speed thru all the shift cycles, to relearn PCM to vehicle and vice versa

IMMO angry lamp,
so then you ask how to hack it not fix it ,right>/?

then failed to scan it and see if its:
1: communications errors.
2: key bad.
3: key transponder bad.

you, cant. hack it.
one guy did, but you dont know how to hack
EPROMS do you. I do, but I'm not doing that here.

also you can call key shop
and some do house calls.
and they reprogram the key for you on the spot.
Call them and ask,
my local shop here in town does.

all this is just boring OLD HAT to all mechanics.

Need to reset the key fob on acura 3.5 rl 98 and dont know how

It is a PAIN. You have to be very precise and have good timing. I had to repeat the whole thing about 4 times before it worked. As a side note, a great place to read EVERYTHING about your car is at it is terrific.

• This system accepts up to two transmitters.
• Entering the programming mode cancels all learned
transmitter codes, so none of the previously
programmed transmitters will work. You must
reprogram all the transmitters once you're in the
programming mode.

1. Open the driver's door.

2. Push up the driver's door master power door lock to
the unlock position. Hold it there for the rest of this

3. Insert the key in the ignition switch, then remove it.
Repeat this four more times within 10 seconds.
(Steps 3 and 4 must be completed within 10
seconds, or the system will exit the programming

4. Insert the key in the ignition switch. Make sure the
power door locks cycle to indicate that the system
has entered programming mode.

5. Press the "LOCK" or "UNLOCK" button on the
transmitter. Make sure the power door locks (all
except the driver's door) cycle to indicate that the
transmitter has been accepted.

6. To program a second transmitter, press its "LOCK"
or "UNLOCK" button within 10 seconds.

7. Release the master power door lock switch to exit
the programming mode.

How do I reset the door lock code on a 93 Mercury Grand Marquis if I don't know the current code. I bought the car from a family and the owner had passed away and they don't know the current code.

There is a master default code that will always work no matter how the personal codes are set. Codes are 5 digits and should be on a card hopefully in the owner's manual packet. If you can't find the card, any Ford dealer can retrieve the master code for you. Even if you knew the previous owner's code, you'll need the master code in order to program a personal code of your own.

Good luck.

How to program 01 RX300 key remote?

Change your battery first, then try again. The codes don`t normally erase on their own.
I had a new master key programed this week and watched the process at the dealership. Mine was done with the same diagnostic code reader they use for the entire vehicle, attached under dash via cable,with the master key along side it is like a giant meter. It took about 7 minutes

Lost key

You cannot disable the immobiliser. If it were that easy, any car theif could defeat it by searching the internet. If you dont have any more master keys, you will have to have your local Toyota dealer reseed (reprogram) the immobiliser code, and program new keys for you. It should be about 2 hours labor and cost of keys, but only a dealer can do it. They need to use the Toyota scan tool, and access a Toyota only website with security codes.
