Saab Key Programming
Saab cars manufactured from 1994 have an immobilizer that relies on a set of keys. To add an additional key, you need an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The problem is that it can be quite costly. how to get a saab replacement key thekeylab.co.uk is the reason why you should always have a spare key at hand.
Transponder key
The transponder is a key with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car then examines the signal to determine whether it is identical to the one on the key. If the signals match it will unlock and begin. This is a great way to stop car theft and keep your vehicle secure from thieves.
Transponder keys are a common feature in cars, but you should be aware that they're not as secure as traditional metal keys. The metal component of the traditional key is easily cut and copied, however the transponder is protected by an electronic chip that safeguards it. The chip is equipped with an unique code that is encoded into the car's system to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. The car won't start when the key isn't programmed to match.
It is essential to have an extra Saab key. This is especially important when you live in a rural region that has numerous car thieves. The good news is that it's possible to obtain a replacement key for your Saab without needing to visit an auto dealership and pay the high prices they ask. You can have the replacement key on the spot at a fraction of the cost you would pay at a dealership.
Key for Wired
Saab cars typically come with two keys upon purchase. If you only have one, you should purchase an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially if you're buying a second-hand car.
The next step is to connect the column and row wires to the microcontroller. This is the most laborious part of the project, and will require a lot of soldering. It's not a common way to do it, but you need to plan how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.
After the rows and column are joined then it's time to connect the key switches. To do this, you need to place a diode on each pin on the key switch and solder it. This will protect the pins from current, and prevent them from getting shorted. The diode allows current to only flow in only one direction. It features a visual indicator with a black band that shows the direction in which the current will flow.
Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the user through each step and make the process more straightforward than replacing the car's computer.
Jump-starting the battery
A lot of people keep the set in their trunks to jump start a vehicle in an emergency, but this might not be the best idea for vehicles that are newer. These cars have a variety of digital and electronic devices that communicate with one another. A voltage spike when the battery is connected to another could cause damage to these components and leave your car unable to drive.
Start the working vehicle and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled vehicle's hood. An engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery because this could trigger an ignition source that ignites gasoline in the engine bay.
After the cables have been connected, start the car and let it run about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to return to its original state. It's a good idea purchase a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that your lost keys are not trying to steal the car.
Replacement Case
Saab owners typically only have one car key, and if it is lost, they will be charged. The reason for this is that it's costly to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a backup key in the event of theft or other disaster and the most effective way is to purchase a second key as early as you can. Even when the key is "new" it will not work.
The dealer will charge you the most expensive dollar if you have only one working key. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept the new key without having to replace the whole system. That can save you a significant amount of money. It's less expensive than wait until you lose the sole key.
