15 Reasons Not To Be Ignoring Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 utilize an immobilizer that relies on a set of keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
This can be expensive. This is why it is important to always have a spare key available.
Transponder key
The transponder key is a key with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car is able to check if the signal matches the one on the key. If the signals are in sync it will unlock and begin. This is a great way to protect your vehicle from theft.
Transponder keys are a popular addition to automobiles, but they are not as safe as traditional metal keys. While the metal part of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip is a unique code which is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob and allow it to turn on. The car can only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. The car will not start when the key isn't programmed to match.
The Key Lab to make sure that you have a spare key for your Saab. This is especially true when you live in a rural location where there are many car thieves. The good news is that you can find a new key for your Saab without needing to visit an auto dealer and pay the expensive prices that they ask. You can have a replacement key created on the spot for less than half the cost you would pay at an auto dealer.
Wired key
Saab cars typically come with two keys when they are new. If you have only one, you need to purchase an extra key as soon as you can. This is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.
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 requires a significant amount of soldering. There isn't a standard way to accomplish this, however it is crucial to plan the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 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 that are used for key switches from current and stop them from being shorted. A diode allows the flow of current to be in one direction, and has a a black band visual indicator that indicates the direction current will flow.
A few of the tools that are available at auto parts stores- such as 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 immobilizer information, Sanabria says. The tools connect to the OBD port and guide the customer through the process, making it easier than replacing the computer in the vehicle.
Jumpstarting the battery
The majority of people have a set of jumper cables in their trunk for emergency situations, but jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with digital and computer systems that communicate with one another. A voltage spike when a battery is hooked up to another one could damage these components and render your vehicle undriveable.
Connect the cables to the vehicle that is operating. Let it 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 underneath the disabled car's hood. The engine block is an ideal choice. 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, you can start the car and let it run for about five minutes. Then disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged while you drive, so it can take a while for the battery to go back to normal. You should invest in a second key fob, as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.
Replacement Case
Saab owners typically only have one car key, and if that is lost, they'll be charged. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. In the event of theft or other catastrophe it is advisable to have a spare key. Don't buy a secondhand key, even when 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.
The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a replacement key without having to replace the entire system. That can help you save money. It's also a lot cheaper than waiting until you lose your only key.
