Why We Do We Love Saab Ignition Key Replacement (And You Should Also!)
Saab Key Programming
Saab cars that were built prior to 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required for the addition of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
It can be costly. This is why it is important to always have a spare key available.
Transponder key
The transponder key comes with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car then checks the signal to determine whether it is identical to the one on the key. If the signals match then the car will be able to unlock and start. saab key fob programming thekeylab.co.uk is an excellent way to guard your car against theft.
Transponder keys are an increasingly popular feature in automobiles, however you should be aware they are not as secure as classic metal keys. The metal component of a traditional key can easily be copied and cut, but transponders are protected by an electronic chip that guards it. The chip has a unique code that's programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. But, it's only able to do this if the key fob has a non-modified chip that has been programmed to match the original. Otherwise, the car would refuse to accept the key and will not start.
It is crucial to have an extra Saab key. This is particularly important if you live in a rural location where there are a lot of car burglars. The good news is that you can obtain a replacement key for your Saab without having to go to an auto dealer and pay the high costs that they demand. You can get an original key made on the spot for less than half of what you would spend at a dealership.
Key for Wired
Saab cars typically come with two keys when new. If you only have one, it's an ideal idea to purchase an extra key fob as soon as possible as if you lose it, the car will require a new CIM unit, and the locking cylinders have to be replaced. This can be expensive particularly for used cars.
The next step is to connect the wires for the column and row to the microcontroller. This is the most tedious part of the project, and will require a lot of soldering. There isn't a standard way to accomplish this, however it is essential to determine the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
After the rows and column are joined, it is time to connect the key switches. To do this you must place a diode across each key switch pin and then solder it. This will shield the pins on the key switch from current and prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it comes with a a black band visual indicator that indicates which way the current will flow.
Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it more simple than replacing the computer in the vehicle.
Jump starting the battery
Most people keep an item in their trunk to jump-start their vehicle in the event of an emergency, but it might not be the best option for vehicles with newer technology. These vehicles are equipped with numerous computers and digital devices which communicate with each other. A surge in voltage while a battery is hooked up to another one could damage these components and leave your vehicle unable to drive.
Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood--the engine block is a good option. Do not connect the black cable to the negative terminal of the dead battery because it could spark an ignition that ignites the gasoline in the engine bay.
After the cables have been connected, you should start the car and let it run for about five minutes. Then disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to drop back down. It's a good idea invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince it that your missing keys aren't in the process of trying to steal the car.
Replacement case
Many Saab owners have only one key for their vehicle and if they lose it, it's going to cost them. It's expensive to purchase 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. But don't buy a used key, even it's "new." Keys that are claimed as new from a second-hand store will not be effective and are almost guaranteed to fail in the crucial moment.
Most locksmiths aren't able to help when you only have one working key and the dealer will charge top dollar to replace the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without having to replace the entire system. This can save you a significant amount of money. It's also cheaper than waiting until you lose your sole key.
