Old Buick GL8 can unlock but not lock the car may be due to a problem with the central control box or the central lock being stuck, the owner needs to check and repair it. The dimensions of the Buick GL8 are 5219mm in length, 1878mm in width, and 1799mm in height, with a wheelbase of 3088mm. The following is an introduction to the Buick GL8: Configuration: Equipped with Buick's advanced intelligent driving assistance system, providing 20 advanced intelligent driving assistance functions including LCC Lane Centering Intelligent Cruise, TJA Traffic Jam Assist, HOD Hands-Off Detection, DOW Door Opening Warning, etc. Power: Equipped with General Motors' latest Smart-Propulsion intelligent driving technology, featuring a flagship powertrain combination of the eighth-generation Ecotec 2.0T variable cylinder turbocharged engine and a 9-speed HYDRA-MATIC intelligent transmission, capable of outputting 174kW and 350Nm, with a combined fuel consumption of only 7.9L/7.8L per 100km. The 9-speed intelligent transmission and the newly equipped ETRS electronic gearshift make gear shifting more responsive and power output smoother and more stable.
I've been driving a Buick GL8 for almost ten years and have encountered similar issues several times. The car can be unlocked but not locked, mainly due to problems with the door lock system, which is common in older vehicles. First, check the battery in the remote control; low power can cause signal transmission failure. Try replacing it with a new one—it only costs a few bucks. If that doesn't work, it might be the lock actuator motor that's broken; that little thing gets stuck and doesn't move, so pressing the lock button gets no response. Loose wiring connections can also be the culprit, especially in older cars where the wiring harness has aged and causes poor contact. I recommend manually locking the doors at night to avoid too much risk. This issue is quite common in older cars, and timely maintenance can solve it. If you're handy, you can remove the door panel and adjust it yourself—it's a hassle-free solution.
