saab spare key Key Programming

saab Ignition key replacement cars manufactured since 1994 use an immobilizer system based on a set of keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

This can be expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder can be described as a key with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car then examines the signal to determine if it matches that of the key. If the signals match it will open itself and begin. This is a great way to stop car theft and keep your car safe from thieves.

Transponder keys may be a popular addition to automobiles, but they are not as safe as traditional metal keys. While the metal component of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code encoded into the car's system to identify it.

The car will recognize the Saab keyfob and permit it to turn on. The car can only recognize the key fob if it has a chip that is unmodified and programmed to match. Otherwise, the car would reject the key and refuse to start.

It's essential to ensure that you have an extra key for your saab 93 replacement key. This is especially important if you reside in a rural area with many car thieves. The good thing is that you can find a new key for your Saab without needing to visit a dealer and pay the high costs they ask. You can have a replacement key made on the spot for less than half of the cost you would pay at the dealership.

Wired key

saab key fob cars are usually provided with two keys. If you only have one, it is recommended to purchase an additional key fob as quickly as you can in case you lose it the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be expensive especially for used vehicles.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most tedious part of the project and will require lots of soldering. There is no standard method to accomplish this, however it is essential to determine the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So 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 key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and prevent them from being shorted. A diode only allows the current to flow in a single direction, and has a an indicator in black 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 -- may help customers in the shop, or even DIY users in some cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into 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

A majority of people keep a set in their trunk to start a vehicle in an emergency, but it might not be the best idea for cars with more modern technology. These cars have a variety of digital and computer systems that communicate with each other. A surge in voltage when batteries are connected to another could cause damage to the components making your car unusable.

Start the working vehicle and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that is good. (It will read "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 choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline inside the engine compartment.

Once the cables are connected the vehicle that has been disabled and let it run for about five minutes before you disconnect the cables in reverse order. Be aware that the battery of the saab key 9-3 gets recharged while you drive, so it will take a while for the battery to go back down again. You should invest in another key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Saab owners typically only have one car key, and if it is lost, they'll be charged. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a backup key in case of theft or any other catastrophe and the best option is to buy an extra key as quickly as you can. Even it's "new" it will not work.

The dealer will charge you top dollar if you only have one working key. 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 could save you a great deal of money. It's also less expensive than waiting until you lose the only key.
