Saab Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system based on coded keys. The addition of a key requires a new transponder, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The problem is that this can be quite costly. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder is a type of key with an electronic chip. The chip transmits a signal when the key is placed into the ignition. The car then checks the signal to determine whether it matches the one in the key. If the signals are in sync, the car will unlock and begin. This is a great way to protect your car from theft.

Transponder keys are a favored feature in automobiles, but you should be aware that they are not as secure as classic keys made of metal. The metal portion of a traditional key is easily cut and copied, whereas transponders are protected by an electronic chip which protects it. The chip contains a unique code which is programmed into a car's computer in order to identify it.

When a Saab Key programmer key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. The car won't start in the event that the key has not been programmed to match.

It is vital to have an extra Saab key. This is especially important especially if you live in a rural area with numerous car thieves. You can obtain a replacement key for your Saab by going to the dealership without paying expensive prices. You can have a replacement key created on the spot for less than half the cost you would pay at dealerships.

Key for Wired

Saab cars usually come with two keys when new. If you only have one, it's recommended to purchase an additional key fob as soon as possible as if you lose it the car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This can be costly especially for used vehicles.

The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and will require a large deal of soldering. There is no standardized way to accomplish this, but it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode over each pin of the key switch and solder it. This will protect the pins from current, preventing them from being shorted. The diode allows current to only flow in only one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.

Sanabria says that a few of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunks in case of emergency, but jumping a battery for newer cars might not be the best idea. They have numerous digital and computer systems that communicate with each other. A surge in voltage when a battery is hooked up to another could cause damage to these components and render your car unable to drive.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline inside the engine compartment.

After the cables have been connected, you can begin the car and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It will take a while for it to recharge again. It is recommended to purchase a second key fob, saab key programmer when you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab 93 replacement key owners only have one key for their car and saab Key Programmer if they lose it, it's going to cost them. The reason is that it's expensive to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in case of theft or other disaster and the most effective way is to purchase a second key as soon as you can. Even if the key is "new" it will not work.

The majority of locksmiths won't be able to help with a single working key and the dealer will charge high fees to replace the computer in your vehicle for a replacement. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without replacing the entire system. This can save you a lot of money. It's less expensive than waiting until you lose the only key.
