Five Killer Quora Answers On Saab Ignition Key Replacement

Saab Key Programming

Saab cars made since 1994 feature an immobilizer system based on keys that are coded. A new transponder is required for addition of an extra key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The issue is that this could be very expensive. This is the reason why you should always keep a spare key in your possession.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal to car when it is inserted into ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are the same the car will then unlock itself and begin. This is a great method to deter auto theft and keep your vehicle safe from thieves.

Transponder keys are an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. While the metal component of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code that's programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. However, it can only do this if your key fob is unmodified and has a chip that has been programmed to match the original. Otherwise, the car would reject the key and not start.

It's crucial to ensure that you have an extra key for your Saab. This is especially important especially if you live in a rural location that has numerous car thieves. You can purchase a new key for your saab ignition key - related website - by going to the dealership and not paying their high prices.

Key for Wired

Saab cars typically come with two keys when they're new. If you have only one, it is recommended to purchase an extra key fob as soon as possible in case you lose it, the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be costly especially for used vehicles.

The next step is to wire the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. It's not a common way to go about it, but you need to determine how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this, put a diode over each pin of the key switch and solder it. This will shield the pins from current, and prevent them from being cut off. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.

Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in certain cases create replacement key for saab 93 keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunk for emergency situations, but jumping a battery in newer cars might not be the most efficient option. These cars have a variety of electronic devices and computers that communicate with each other. A surge in voltage when a battery is connected to another battery could damage the components, rendering your car undriveable.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the non-working one. 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 a clean, unpainted metal surface underneath the car's hood. The engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can begin the car and let it run for about five minutes. Then, disconnect them in reverse. The battery in the saab car key replacement 9-3 will charge as you drive. It will take a while for it to drop back down. It is recommended to purchase a second key fob, when you can. Replacing the original 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 car and if they lose it, the cost will be. It's costly to add keys and will require replacing the CIM or TWICE for older models. In the event of theft or any other disaster, it is best to have an extra key. Even if the key is "new" it will not work.

The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without replacing the entire system. This can save you a significant amount of money. It's much cheaper than waiting until you lose your only key.
