Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer system built on coded keys. A new transponder is required in order to enable the addition of an additional key, as well as special programming. saab key replacement near me is usually done by the dealer with a specialized Tech2 diagnostic tool.
The issue is that it can be very costly. It is recommended to always have an extra set of keys in your possession.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal back to the car when it is put into the ignition. The car then analyzes the signal to determine whether it matches the one that is in the key. If the signals are the same, the car will unlock itself and start. This is a great method to protect your car from theft.
Transponder keys may be an extremely popular accessory for cars, but they're not as safe as traditional metal keys. The metal component of a traditional key can easily be cut and copied, however transponders are protected by an electronic chip that protects it. This chip has a unique code embedded into the car's computer to identify it.
The car will recognize the Saab keyfob and allow it to turn on. However, it will only do this if your key fob has a non-modified chip that has been programmed to match. The car won't start when the key isn't programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is especially true especially if you reside in a rural area where there are numerous car thieves. The good thing is that you can find a replacement key to your Saab without needing to visit a dealership and pay the expensive prices that they ask. In most cases, you can have a new key made on-the-spot at a fraction of the cost of what you would pay at an auto dealer.
Key for Wired
Saab cars are usually delivered with two keys. If you only have one, it is an ideal idea to purchase an extra key fob as soon as is possible as if you lose it the car will require the replacement of a CIM unit and the locking cylinders will have to be replaced. This could be expensive, especially if you are buying a second-hand car.
The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There is no standard method to do this, but it is crucial to plan the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 5 rows and 17 column.
After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode only allows the current to flow in a single direction, and it has an indicator of black color that indicates the direction in which current will flow.
Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in some cases programme replacement keys and recover lost immobilizer data, Sanabria says. The tools connect to OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.
Jump-starting the battery
A majority of people keep an assortment of tools in their trunk to jump-start their vehicle in an emergency, but this might not be the best idea for newer cars. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A voltage surge when a battery is connected to another battery could damage the components, rendering your car undriveable.
Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface under the hood of your disabled vehicle. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal on the dead battery, as it could ignite a spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that is disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 will recharge as you drive. It will take some time for it to fall back. It's a good idea buy a spare key fob as soon as you can, since 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 in the process of trying to steal the car.
Replacement case
Saab owners often only have one car key, and if it is lost, they'll be charged. It's expensive to buy an additional key and it requires replacing the CIM or TWICE in the case of older models. It is recommended to have a backup key in case of theft or other disaster and the best option is to purchase an extra key as early as you can. Don't purchase a used key, even the case that it's "new." Claimed-new keys from aftermarket sellers will not work and are likely to fail at the crucial moment.
The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without the need to replace the entire system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose your one key.
