saab car key replacement Key Programming

Saab cars manufactured since 1994 come with an immobilizer system built on coded keys. A new transponder is required for the addition of a second key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that it can be very expensive. It is recommended to always have an extra set of keys in your possession.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car will then check the signal to determine if it matches the one on the key. If the signals are identical it will open itself and begin. This is a great way to deter car theft and keep your vehicle safe from thieves.

Transponder keys are a common feature in automobiles, but it is important to know that they aren't as secure as classic keys made of metal. The metal part of the traditional key can be easily cut and copied, however transponders are protected by an electronic chip which protects it. The chip has a unique code which is programmed into a car's computers in order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key has not been programmed to match.

It is vital to have a spare Saab Ignition Key key. This is especially important for those who live in a rural area that is home to numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership and not paying their pricey cost. In most instances, you can get a new key made on-the-spot for less than half the cost of what you'd pay at an auto dealer.

Key for Wired

saab key programmer cars usually come with two keys when new. If you have only one, it's recommended to purchase an extra key fob as soon as you can in case you lose it, your car will require a new CIM unit and the locking cylinders will need to be replaced. This can be expensive especially for used vehicles.

The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to go about it, but you should consider how you will connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are joined It is now time to connect the key switches. To do this, place a diode on each key switch pin and then solder it. This will protect the pins of the key switch from current and keep them from being shorted. A diode permits current to only flow in one direction. It features a visual indicator, a black band, that indicates the direction in which current will flow.

Sanabria states that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 are able to assist customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and guide the user through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

The majority of people have an item in their trunk to start a car in an emergency, but this might not be the best idea for cars with more modern technology. These vehicles are equipped with many digital and computers that communicate with one another. A voltage spike when a battery is connected to another one could cause damage to the parts making your car unusable.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface beneath the hood of the damaged car. The engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, you need to start the vehicle and let it run for about five minutes. Then disconnect the cables in reverse. Remember that the battery on your Saab 9-3 is charged when you drive, so it may take some time for the battery to go back down again. It is a good idea to buy a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your lost keys aren't trying to steal the car.

Replacement case

Many saab keys owners only have one key for their car and if they lose that the cost will be. The reason is that it's not cheap to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a spare key in the event of theft or other disaster the best solution is to purchase a second key as quickly as you can. But don't buy a used key, even when it's "new." Keys that are claimed to be new from aftermarket sellers will not perform and are almost certain to fail at the critical moment.

The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without the need to replace the entire system. That can save you lots of money. It's also much less expensive than waiting until you lose your one key.
