Saab Key Programming
Saab cars made since 1994 have an immobilizer system built on coded keys. A new transponder is required to allow the addition of a second key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
This can be expensive. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder key comes with an electronic chip that sends a signal to the car when it is put into the ignition. The car then examines the signal to determine whether it matches that of the key. If the signals match it will open itself and start. This is a great method to prevent auto theft and keep your car safe from thieves.
Transponder keys could be an extremely popular accessory for automobiles, but they are not as safe as traditional keys made of metal. The metal portion of a traditional key is easily cut or copied, while the transponder is protected by an electronic chip that protects it. This chip contains an unique code that's programmed into a car's computers in order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob is unmodified and has a chip that has been programmed to match it. Otherwise, the car would reject the key and refuse to start.
It is important to have a spare Saab key. This is especially important especially if you reside in a rural area where there are many car thieves. The good thing is that you can get a replacement key for your Saab without having to go to a dealer and pay the high prices that they charge. In most cases, you can have a new key made on-the-spot for less than half the cost of what you'd pay at a dealer.
saab 9-3 key not accepted contact service g28carkeys.co.uk come with two keys when they're new. If you own only one, you need to purchase an additional key as fast as you can. This is because if you lose it the car will require a new CIM and the locking cylinders replaced. This can be costly particularly for used cars.
The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There isn't a standard way to do this, but it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 column.
Once the rows and columns are soldered, it's the time to connect them to key switches. To do this you must place a diode across each key switch pin and then solder it. This will shield the pins on the key switch from current and stop them from being shorted. A diode only allows the current to flow in a single direction, and it has an indicator in black that indicates the direction current will flow.
Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.
Jumpstarting the battery
A majority of people keep an item in their trunks to jump-start their vehicle in an emergency, but it may not be a good idea for cars with more modern technology. These cars have a variety of digital and electronic devices that communicate with one another. A surge in voltage while a battery is hooked up to another one could damage these components and leave your car undriveable.
Start the vehicle you are using and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled car's hood. The engine block would be a good option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline in the engine compartment.
Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to fall back. It is a good idea to invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and a special program to convince it that your missing keys aren't attempting to steal the car.
Replacement Case
Saab owners usually have only one car key, and if that is lost, they will be charged. It's expensive to buy keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft, or any other disaster, it is best to have an extra key. Even when the key is "new" it will not function.
The majority of locksmiths won't be able to help if you have only one working key, and the dealer will charge you top dollar to replace the computer in your vehicle to make a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key without having to replace the whole system. This could save you a lot of money. It's also cheaper than waiting until you lose your one key.
