Saab Key Programming
Saab cars made since 1994 come with an immobilizer system that is based on codes for keys. To add an additional key, you need a new transponder, as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.
The problem is that this can be very costly. This is why you should always have a spare key on hand.
Transponder key
The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is put into the ignition. The car then checks to see whether the signal matches with the one on the key. If saab 9-3 key replacement TheKeyLab are identical it will open itself and start. This is a great method to stop auto theft and keep your car safe from thieves.
Transponder keys are a favored feature in cars, but you should be aware they're not as secure as classic metal keys. The metal component of the traditional key is easily copied and cut, but transponders have an electronic chip which protects it. This chip contains an unique code that is programmed into a car's computer in order to identify it.
The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. Otherwise, the car would reject the key and refuse to start.
It's essential to ensure that you have a spare key for your Saab. This is particularly true especially if you live in a rural location that has many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying high cost. In most cases, you can have an original key made on the spot at a fraction of the price of what you would pay at dealerships.
Wired key
Saab cars usually come with two keys upon purchase. If you have only one, it's recommended to purchase an extra key fob as quickly as you can since if you lose it, your car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be costly particularly for used cars.
The next step is to connect the wires for columns and rows to your microcontroller. This is the most tedious component of the project and it will require lots of soldering. There isn't a standard way to accomplish this, however it is essential to determine the way you'll route and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect for this keyboard. It includes 5 rows and 17 columns.
After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from getting shorted. A diode allows the flow of current to be in one direction, and it has the black band as a visual indicator that indicates the direction in which current will flow.
Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jump starting the battery
A majority of people keep an assortment of tools in their trunks to start a car in an emergency, but it may not be the best idea for newer cars. They have numerous electronic devices and computers that communicate with each other. A voltage surge when batteries are connected to another can fry the components making your car inoperable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could create a spark, which would ignite the gasoline that is in the engine compartment.
Once the cables are connected, turn on the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to return to its original state. It's a good idea to purchase a spare fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't in the process of trying to steal the car.
Replacement case
Saab owners typically only have one car key, and if it is lost, they will be charged. The reason for this is that it's expensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a spare key in the event of theft or any other catastrophe and the most effective way is to buy an extra key as early as you can. However, don't purchase a secondhand key, even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't perform and are almost certain to fail in the most critical moment.
The majority of locksmiths won't be able to help if you have only one working key and the dealer will charge you high fees to replace the computer in your vehicle to make a replacement. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a replacement key without the need to replace the entire system. This could save you lots of money. It's also cheaper than waiting until you lose your only key.
