5 Killer Quora Answers On Saab Ignition Key Replacement

Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer system based on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that this could be very expensive. This is why you should always have a spare key available.

Transponder key

The transponder is a key equipped with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If the signals match the car will then unlock itself and start. This is a great way to protect your car from theft.

Transponder keys are an increasingly popular feature in vehicles, but you should be aware they're not as secure as traditional metal keys. While the metal part of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip has a unique code which is programmed into the car's computer in order to identify it.

The car will recognize the saab 9-3 replacement key keyfob, and allow it to be turned on. However, it will only do so if the key fob has a non-modified chip that has been programmed to match. Otherwise, the car will refuse to accept the key and will not start.

It's important to make sure that you have an extra key for your saab 93 key fob. This is particularly important if you live in a rural location where there are a lot of car thieves.

Wired key

saab ignition key replacement cars typically come with two keys when new. If you have only one, it is recommended to purchase an extra key fob as soon as is possible, because if you lose it, the car will require an entirely new CIM unit and the locking cylinders will need to be replaced. This can be costly especially for used vehicles.

The next step is to wire the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a good amount of soldering. There is no standard method to accomplish this, however it is essential to determine the way you'll route and solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, you need to place a diode across each pin on the key switch and solder it. This will protect the pins from current, and prevent them from being shortened. The diode allows current to only flow in one direction. It has a visual indicator, a black band, that shows the direction in which the current will flow.

Sanabria says that some of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508, can help customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. 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 trunk for emergency situations however, jumping a battery in newer automobiles might not be the best option. These vehicles are equipped with many computers and digital devices which communicate with one another. A surge of voltage when a battery is connected to another could cause damage to the components making your car inoperable.

Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block would be an excellent choice. Don't connect the black cable to the negative terminal of the dead battery as it could ignite a spark that ignites the gasoline in the engine bay.

Replacement case

Saab owners often only have one car key, and if it is lost, they'll be charged. The reason for this is that it's costly to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a spare key in the event of theft or other disaster the best solution is how to get a saab replacement key buy an extra key as soon as you are able to. Don't purchase a used key even when 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 dealer will charge you the highest dollars if you only have one working key. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This can save you a lot of money.
