Saab Key Programming

saab key battery cars built since about 1994 come with an immobilizer system made up of coded keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

The problem is that this could be extremely expensive. You should always keep an extra set of keys at hand.

Transponder key

The transponder is a piece of key with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car then checks to see whether the signal matches with the one on the key. If both signals match the car will then unlock itself and begin. This is a great method to prevent car theft and keep your car safe from thieves.

Transponder keys are a common feature in automobiles, however you should be aware they are not as secure as classic keys made of metal. The metal component of a traditional keys can be easily cut and copied, however transponders have an electronic chip which protects it. The chip has a unique code that is inserted into a car's computer in order to identify it.

When a Saab key fob is used, SAAB key replacement the car recognizes it and allows it to turn on. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match. In the absence of that, the car will reject the key and not start.

Wired key

Saab cars typically come with two keys upon purchase. If you only have one, it is an ideal idea to purchase an extra key fob as soon as possible since if you lose it, the car will require an entirely new CIM unit and the locking cylinders have to be replaced. This can be expensive especially for used vehicles.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There is no standard method to do this, but it is important to think about the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It includes 5 rows and 17 columns.

After the rows and column are joined, it is time to connect the key switches. To do this, place a diode over each key switch pin and solder it. This will protect the pins from current, preventing them from being shorted. A diode allows current to only flow in one direction. It features a visual indicator, a black band, that shows which way current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in some cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools connect to OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.

Jump starting the battery

The majority of people have a set of jumper cables in their trunk for emergencies, but jumping a battery on modern vehicles may not be the best option. They have numerous digital and Saab Key Replacement electronic devices that communicate with one another. A voltage surge when the battery is connected another could cause damage to the components making your car inoperable.

Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of the affected vehicle. The engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery as it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle that is disabled and let it run for about five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It will take a while for it to drop back down. It's a good idea to purchase a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and a special program to convince it that the lost keys are not trying to steal the car.

Saab owners usually only have one car key, and if it is lost, they will be charged. The reason is that it's not inexpensive to buy a new key, and this 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 the event of theft or other disaster the best solution is to purchase a second key as quickly as you can. Don't purchase a used key even it's "new." Keys that are claimed-new from a second-hand store will not be effective and are almost guaranteed to fail in the most critical moment.
