Saab Key Programming
Saab cars built from 1994 have an immobilizer system that relies on a set of keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key on hand.
Transponder key
The transponder is a piece of key with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car then analyzes the signal to see whether it is the same as the one in the key. If the signals are in sync then the car will be able to unlock and begin. This is a great method to stop car theft and keep your vehicle safe from thieves.
Transponder keys can be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. While the metal component of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code that is programmed into the car's computers to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it can only do this if the fob has a non-modified chip that has been programmed to match the original. The
Car Key Maker won't start in the event that the key is not programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is especially true when you live in a rural location where there are numerous car thieves. You can obtain a replacement key for your
saab car key replacement by visiting the dealership and not paying their expensive costs. In the majority of cases, you can have a new key created on-the-spot for less than half the price of what you'd pay at dealerships.
Key for Wired
saab 9-3 key cars usually come with two keys upon purchase. If you only have one, it's best to acquire an extra key fob as soon as possible in case you lose it the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be costly especially for cars that are used.
The next step is to connect the wires for the column and row to the microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There isn't a standard method to do it, but you need to plan how to connect and solder each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It includes 5 rows and 17 column.
Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from being shortened. The diode allows current to only flow in one direction. It is equipped with a visible indicator of a black line that shows which way current will flow.
Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY customers in some cases program replacement keys and restore
lost saab keys 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.
Jump-starting the battery
Most people keep a few sets of jumper cables in their trunk for emergencies, but jumping a battery on newer cars might not be the best idea. These vehicles are equipped with many electronic devices and computers that communicate with each other. A surge in voltage while a battery is hooked up to another one could damage the components and render your vehicle undriveable.
Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is a good option. Do not connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition spark that ignites the gasoline in the engine bay.
After the cables have been connected, begin the car and allow it to run for around five minutes. Then disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to return to its original state. It is recommended to purchase an additional key fob as soon as possible. Replacing the one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Many Saab owners only have one key for their vehicle and if they lose it, they'll be charged. It's costly to add keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft, or any other calamity, it is best to have an extra key. However, don't purchase a secondhand key, even it's "new." Claimed-new keys purchased from third-party sellers won't be effective and are almost guaranteed to fail at the crucial moment.
The majority of locksmiths won't be able to help with a single working key and the dealer will charge high fees to replace the computer in your car to make a replacement. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without replacing the entire system. That can save you a significant amount of money. It's also less expensive than waiting until you lose your one key.
