11 Ways To Fully Redesign Your Saab Ignition Key Replacement
Saab Key Programming
Saab cars produced from 1994 have an immobilizer that relies on a set of keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
This can be expensive. Always keep an extra set of keys on hand.
Transponder key
The transponder can be described as a key that is equipped with an electronic chip. This chip sends out a signal when the key is inserted into the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are in sync, the car will unlock and begin. This is a great method to prevent auto theft and keep your car secure from thieves.
Transponder keys are an increasingly popular feature in cars, but it is important to know that they're not as secure as classic metal keys. The metal component of the traditional key is easily cut and copied, whereas transponders have an electronic chip which protects it. The chip has a unique code embedded into the car's computer to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do this if your key fob is unmodified and has a chip that has been programmed to match. webpage won't start in the event that the key has not been programmed to match.
It is vital to have an extra Saab key. This is especially true especially if you reside in a rural region where there are numerous car thieves. You can purchase a new key for your Saab by visiting the dealership and not paying their high cost. In the majority of instances, you can get a new key made on-the-spot at a fraction of the price of what you would pay at an auto dealer.
Key for Wired
Saab cars are usually provided with two keys. If you only have one, it is best to acquire an additional key fob as soon as possible since if you lose it, the car will require a new CIM unit and the locking cylinders need to be replaced. This can be expensive, especially for used cars.
The next step is to connect the row and columns wires to your microcontroller. This is the toughest part of the project and will require lots of soldering. There's no standard way to go about it, however, you should plan how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and keep them from being shorted. The diode will only allow the current to flow in a single direction, and it comes with a a black band visual indicator that indicates the direction current will flow.
Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY customers in certain cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and guide the customer through the process, making it more simple than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep a few sets of jumper cables in their trunks for emergency situations, but jumping a battery on modern cars might not be the best idea. These cars are equipped with a variety of electronic devices and computers that communicate with one another. A voltage surge when batteries are connected to another battery could damage the components making your car unusable.
Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the disabled one. 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 to a clean, unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a good alternative. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline inside the engine compartment.
Once the cables are connected, start the vehicle that has been 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 be recharged while you drive. It may take a while it to drop back down. It is a good idea to buy a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince it that your missing keys aren't in the process of trying to steal the car.
Replacement case
Saab owners usually only have one car key, and if it is lost, they will be charged. It's costly to add a key and requires replacing the CIM or TWICE for older models. In the event of theft or any other calamity, it is best to have a spare key. Even if the key is "new" it won't work.
Most locksmiths aren't able to help in the event that you only have one working key and the dealer will charge you high fees to replace the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM 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 less expensive instead of waiting until you loose the only key.
