Why We Love Saab Ignition Key Replacement (And You Should Also!)
Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer feature built on coded keys. A new transponder is required to allow the inclusion of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The problem is that it can be extremely expensive. You should always keep a spare set of keys on hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car will check to see whether the signal matches the one on the key. If the signals are in sync the car will then unlock and start. This is a great way to deter car theft and keep your car secure from thieves.
Transponder keys are a common feature in automobiles, but you should be aware that they're not as secure as traditional metal keys. While the metal parts of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip has an individual code that is encoded into the car's system to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match. The car won't start in the event that the key has not been programmed to match.
It's important to make sure that you have a spare key for your Saab. This is especially true when you live in a rural area where there are many car thieves. You can purchase a new key for your Saab by visiting the dealership, without having to pay their pricey prices. In the majority of instances, you can get an original key made on the spot at a fraction of the cost you'd pay at a dealer.
Key for Wired
Saab cars are usually supplied with two keys. If you own only one, you need to purchase an additional key as quickly as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be costly particularly for used cars.
The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There isn't a standard method to do it, but you should determine how to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 column.
After the rows and column are soldered together after which it is 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 also prevent them from being shorted. The diode allows current to only flow in one direction. It is equipped with a visible indicator that is black, that indicates which direction current will flow.
Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may help shop customers or even DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the car's computer.
Jump starting the battery
Most people keep a few sets of jumper cables in their trunk in case of emergency however, jumping a battery in newer cars might not be the most efficient option. These vehicles have many electronic devices and computers that communicate with one another. A surge in voltage while the battery is connected to another can fry these components and leave your vehicle undriveable.
Start the vehicle that is working and let it run for about two minutes before connecting the cables to the non-working one. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the damaged vehicle. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery, as it could spark an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, start the vehicle that has been disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. Be aware that the battery in your Saab 9-3 is recharged when you drive, so it will take a while for the battery to go back to normal. You should consider purchasing an additional key fob as soon as possible. Replacing saab 93 key fob replacement that works requires the installation and programming of a new computer chip.
Replacement Case
Saab owners often only have one car key, and if it is lost, they will be charged. The reason for this is that it's expensive to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a spare key in the event of theft or any other catastrophe and the most effective way is to purchase a second key as early as you can. However, don't purchase a secondhand key even when it's "new." Claimed-new keys from aftermarket sellers will not perform and are almost certain to fail in the most critical moment.
Most locksmiths cannot help you when you only have one working key, and the dealer will charge you for the cost of replacing the computer in your vehicle for a replacement. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without replacing the entire system. This can save you a great deal of money. It's also much less expensive than waiting until you lose your one key.
