saab 9-3 key Key Programming

saab car keys cars manufactured since 1994 feature an immobilizer that relies on coded keys. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

The issue is that this could be very costly. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder is a key equipped with an electronic chip. The chip transmits a signal when the key is put in the ignition. The car is able to check whether the signal matches with the one on the key. If the signals match the car will then open and start. This is a great method to deter auto theft and keep your car secure from thieves.

Transponder keys are a popular feature in automobiles, however it is important to know that they aren't as secure as classic metal keys. While the metal component of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code which is programmed into the car's computer in order to identify it.

When a Saab key fob is used the car recognizes it and allows it how to get a saab replacement key turn on. However, it can only do this if the fob has an unmodified chip that has been programmed to match the original. In the absence of that, the car will reject the key and refuse to start.

It is crucial to have an extra Saab key. This is especially true if you reside in a rural area that is home to many car thieves. You can purchase a new key for your Saab by visiting the dealership, without having to pay their expensive cost. In most instances, you can get a brand new key made right on the spot for less than half the cost you would pay at the dealer.

Wired key

Saab cars typically come with two keys when they are new. If you only own one, you should purchase an additional key as fast as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is to connect the row and columns wires to your microcontroller. This is the most laborious part of the project and it will require lots of soldering. There is no standardized way to do this, but it is crucial to plan the route you'll take and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

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

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in some cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep the set in their trunks to jump-start a vehicle in an emergency, but this might not be the best option for vehicles with newer technology. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A surge in voltage when the battery is connected another battery could damage the components making your car inoperable.

Start the working vehicle 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 battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood--the engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline that is in the engine compartment.

Once the cables are connected, you can start the vehicle you are not using and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 is recharged as you drive. It will take some time for it to drop back down. It's a good idea to purchase 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 the lost keys aren't attempting to steal the car.

replacement Saab 9-3 key Case

Many Saab owners have only one key for their vehicle and if they lose it, the cost will be. The reason for this is that it's costly to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other catastrophe it is best to have an extra key. However, don't purchase a secondhand key, even when it's "new." Keys that are claimed to be new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the crucial moment.

Most locksmiths cannot help you when you only have one working key and the dealer will charge top dollar to replace the computer in your car to create a replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without having to replace the entire system. This can save you lots of money. It's more affordable than waiting until you lose the sole key.
