Try your spare key. It could be that the primary key you have been using needs to be reprogrammed, which can be done by contacting a dealer. A spare key will have the same microchip technology, and because it has not been heavily used, the microchip will still be good on that key. Depending on your make and model, you might be able to save some money and call a car locksmith and ask about services for reprograming keys if the spare key does not work.
Turn the key to the "On" position in order to reset the pass lock system. Wait for fifteen minutes with the key in the "On" position. If the security light disappears, turn the key to the "Accessories" position and wait for a couple of seconds. Turn the key to the "Off" position and take it out from the lock cylinder. Wait for a couple of seconds and turn the car on as you normally would.
Install a relay that bypasses the security system if your car is using a remote starter. Contact your remote starter dealer or installer to ask about the relay. It is possible to also install the relay if you do not use a remote starter. Install the relay by finding an electrical circuit diagram for your vehicle and locating the security immobilizer circuit. Cut the circuit with wire cutters and solder the bypass wire into the circuit. Test it by turning your car on to make sure that it works.
Take your key to a dealer or a hardware store if you have recently lost a key or replaced the ignition switch. Only some hardware stores are able to duplicate microchipped keys while nearly every dealer will be able to help by making a duplicate key with a microchip.

Reset security ,,ran for like 2 mins then check engine and security light allover again...whats the problem?


The key has a microchip inside of it. If the key is damaged,it will continue to do that. Another possibility is the security ring that goes around the ignition cylinder,OR the ignition cylinder itself. Id get a new key,and have it programmed first,before going any further...OR have someone with a scan tool check the security system for codes.

I had a new key cut for my 2004 accord and replaced the keyless entry pad. The car will not start...does the pad need reprogramed to start the car


If you car has the immobilizer system, the following might help.

The Immobilizer System protects your car from theft. A properly coded ignition key must be used in the ignition switch for the engine to start. If an improperly-coded key (or other device) is used, the engine’s fuel system is disabled.
When you turn the ignition switch to ON (II), the Immobilizer System indicator should come on for a few seconds, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the key.
Turn the ignition switch to LOCK (0), remove the key, reinsert it, and turn the switch to ON (II) again.

Hope this is helpful to you.

Check Engine light P1670


I have a 2000 Volvo S70 as well with the same code. Do you ever have trouble starting your car? I did and that's why I took it to the dealer. Appartently it's the code for the ignition immobilizer system in your car (part of the security system). Specifically, a part call the antenna ring. The antenna ring is the outer portion of your ignition switch on the steering column - the part that lights up and has the following printed on it: 0 - I - II - III. This part is actually a sensor that transmits the code stored in the microchip inside of your key. When this part goes bad it fails to transmit the correct key code to the computer, and cuts the fuel to the engine.

The dealer wanted to charge me $550 for a new antenna ring, two new keys, and software to program the car's computer with the new key codes. I purchased the antenna ring online for $50 and did it myself in 15 minutes - so easy. They claim that you can't replace the antenna ring without new software - lie! You only need the software if you are replacing the keys.

Car is running great.
