The Biggest Issue With Saab Ignition Key Replacement, And How You Can Solve It
Saab Key Programming
Saab cars that were built prior to 1994 feature an immobilizer mechanism that is based on codes for 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 Tech2 diagnostic tool.
The issue is that this can be very costly. It is always advisable to keep a spare set of keys available.
Transponder key
The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are in sync then the car will be able to open and start. This is a great method to stop car theft and keep your vehicle safe from thieves.
Transponder keys could be an extremely popular accessory for cars, but they're not as safe as traditional keys made of metal. While the metal parts of a conventional key can be cut and copied the transponder is protected by an electronic chip. This chip has a unique code that is programmed into the car's computer to identify it.
The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. The car will not start in the event that the key is not programmed to match.
It is crucial to have a spare Saab key. This is particularly important when you live in a rural area that is home to many car thieves. The good thing is that you can find a new key for your Saab without having to go to an auto dealership and pay the hefty prices that they demand. In the majority of instances, you can get a brand new key made right on the spot at a fraction of the cost you'd pay at the dealer.
Key for Wired
Saab cars usually come with two keys when new. If you only have one, you should get an additional key as quickly as you can. This is because if it's lost the car will require a new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.
The next step is to connect the wires of columns and row to your microcontroller. This is the most tedious part of the project, and it will require a lot of soldering. There's no standard way to go about it, but you must determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.
Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put a diode over each pin on the key switch and solder it. saab car key replacement will shield the pins on the key switch from current and prevent them from being shorted. The diode will only allow current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.
Sanabria says that a few of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. The tools connect to OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.
Jumpstarting the battery
Most people keep a few sets of jumper cables in their trunks for emergency situations, but jumping a battery for newer vehicles might not be the best option. These cars have a variety of digital and electronic devices that communicate with one another. A voltage spike when the battery is connected another battery could damage the components making your car inoperable.
Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled 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 cause sparks, which could ignite gasoline in the engine compartment.
Once the cables are connected, you can start the vehicle that has been disabled and allow it to run for around five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge as you drive. It takes a while for it to recharge again. It's a good idea to invest in 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 the system that your lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners only have one key for their car and if they lose it, the cost will be. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other calamity it is advisable to have an extra key. Even if the key is "new", it will not work.
Most locksmiths can't help you if you have only one working key, and the dealer will charge high prices to replace the computer in your vehicle to make a replacement. We can reset and reprogram the EEEPROM of your computer to be able to accept a new key without the need to replace the entire system. This can help you save a significant amount of money. It's also much less expensive than waiting until you lose your only key.
