How to evaluate the transmitter strength of a car key fob and replace its battery on 2017 Volkswagen Jetta?

To test transmitter strength, go to a repair shop with a TPMS tester. For battery replacement, use a flat screwdriver to pull the two halves of the key fob apart, replace the battery, and then put the halves back together. For programming, professional help is recommended, since original fob synchronization requires a scanner and locksmith license. Instructions on aftermarket fobs may be included.
