The Most Underrated Companies To In The Saab Ignition Key Replacement Industry
Saab Key Programming
Saab cars manufactured since 1994 use an immobilizer system based on coded keys. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The problem is that this can be very costly. You should always keep a spare set of keys in your possession.
Transponder key
The transponder is a key equipped with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are identical it will open itself and start. This is a great method to stop car theft and keep your vehicle safe from thieves.
Transponder keys may be an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. The metal component of the traditional key can be easily copied and cut, but the transponder is protected by an electronic chip which protects it. The chip is a unique code that's programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and programmed to match. Otherwise, the car will reject the key and won't start.
It is essential to have an extra Saab key. This is especially important if you live in a rural area where there are a lot of car thieves. The good thing is that you can obtain a replacement key for your Saab without having to go to a dealership and pay the hefty prices that they charge. You can have an original key made on the spot at a fraction of the price you'd spend at dealerships.
Wired key
Saab cars typically come with two keys when they're new. If you only have one, you should get an additional key as soon as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.
The next step is connecting the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There's no standard way to go about it, but you need to determine how to route and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It includes 5 rows and 17 columns.
Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this you must place an inverter over each pin of the key switch and solder it. saab 9-3 key not accepted contact service will shield the key switch pins from current and also prevent them from being shorted. A diode can only allow the current to flow in a single direction, and it also has a the black band as a visual indicator that shows the direction in which current will flow.
A few of the tools that are 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 some cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer in the vehicle.
Jumpstarting the battery
Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery for newer vehicles may not be the best idea. These cars are equipped with a variety of computers and digital devices which communicate with one another. A voltage surge when the battery is connected another one could cause damage to the parts making your car inoperable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on 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 car's hood--the engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline that is in the engine compartment.
After the cables have been connected, you can begin the car and let it run for about five minutes. Then, disconnect them in reverse. Be aware that the battery in your Saab 9-3 is charged during your drive, which means it could take a while to get the battery back down again. You should purchase another key fob as soon as you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement case
Saab owners often only have one car key, and if that is lost, they will be charged. It's expensive to add a key and requires replacing the CIM or TWICE for older models. It is best to have a spare key in case of theft or other disaster and the most effective way is to purchase a second key as quickly as you can. However, don't purchase a secondhand key even if it's "new." Keys that are claimed-new purchased from third-party sellers won't perform and are almost certain to fail at the critical moment.
The dealer will charge you top dollar for only one working key. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key without having to replace the whole system. This can save you a lot of money. It's much cheaper than waiting until you loose the only key.
