Saab Key Programming

Saab cars made from 1994 have an immobilizer that relies on key codes. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that this could be extremely expensive. It is always advisable to keep a spare set of keys available.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is put into the ignition. The car will then check the signal to see whether it is the same as that of the key. If the signals match the car will then open and start. This is a great method to deter car theft and keep your car safe from thieves.

Transponder keys are an increasingly popular feature for cars, but they're not as secure as traditional metal keys. The metal component of the traditional key can be easily cut and copied, whereas the transponder is protected by an electronic chip that safeguards it. The chip is equipped with a unique code that is encoded into the car's system to identify it.

The car will recognize the saab replacement key programming ignition key (reviews over at Telegra) 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. Otherwise, the car will refuse to accept the key and will not start.

Saab cars are usually delivered with two keys. If you only own one, you should purchase an extra key as soon as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly, especially for used cars.

The next step is connecting the wires for columns and rows to your microcontroller. This is the toughest component of the project and will require lots of soldering. There's no standard way to accomplish this, however it's important to plan out the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 columns.

After the rows and column are joined, it is time to connect the key switches. To do this you must place an inverter over each key switch pin and then solder it. This will protect the pins on the key switch from current and keep them from being shorted. The diode allows current to only flow in one direction. It is equipped with a visible indicator of a black line that indicates the direction in which current will flow.

Some of the tools available 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 instances create replacement saab 9-3 key keys and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

The majority of people have a set in their trunk to jump-start a car in an emergency, but this might not be the best idea for cars with more modern technology. These vehicles are equipped with computers and digital devices which communicate with one another. A voltage surge when batteries are connected to another can fry the components, rendering your car undriveable.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block is an ideal choice. Do not connect the black cable to the negative terminal of the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can begin the car and allow it to run for around five minutes. Then, disconnect them in reverse. The battery in your saab ignition key replacement 9-3 will be recharged while you drive. It may take a while it to recharge again. It's a good idea to buy a spare key fob as soon as you can, because replacing the only working one requires the installation of a new computer module and a special program to convince it that the lost keys aren't trying to steal the car.

Replacement case

Many saab 9-3 key fob programming owners only have one key for their car and if they lose that they'll be charged. It's costly to add a key and requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or any other catastrophe and the best option is to purchase a second key as quickly as you can. Even when the key is "new", it will not work.

The dealer will charge you top dollar for only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without the need to replace the entire system. This can help you save money. It's more affordable instead of waiting until you lose your only key.
